Australia – Landlines and Mobile Phones

What are the international dialling codes for Australia, and what are the area codes for the most popular expat destinations?

Australia’s international country code is +61, which must be dialled before any Australian number when placing a call from another country. The national trunk access code — the digit 0 that Australians dial before area codes domestically — is omitted when calling from overseas. As a practical example, the Sydney area code of 02 becomes simply 2 in the international format, making a Sydney number such as (02) 1234 5678 appear as +61 2 1234 5678 when dialled from abroad.

Australian landline numbers consist of eight digits and are conventionally grouped as xxxx xxxx. When calling a number in a different region from within Australia, you dial the trunk code 0, then the area code, followed by the eight-digit local number. Mobile phones and internet-based calling services follow the same format when dialling out of their home area.

Each state and territory has its own area code for fixed-line services. New South Wales — including Sydney — shares the 02 code with the Australian Capital Territory. Victoria uses 03, as does Tasmania. Queensland’s code is 07. Western Australia, South Australia, and the Northern Territory all share the 08 code, which covers a vast geographic area spanning much of the country’s western and central regions.

Australian mobile numbers always begin with 04, followed by eight digits, and are written in the format 04xx xxx xxx. Unlike landlines, mobile numbers carry no regional significance — the same number format applies regardless of which state the user lives in. When calling an Australian mobile from outside the country, simply replace the leading 0 with +61 to reach the handset anywhere in Australia.

The 1800 prefix denotes freecall numbers, which are ten digits in total. These are widely used by government departments and large service organisations, and are generally free to call from a landline; most providers also allow free calls to 1800 numbers from mobiles, though it is always worth confirming this with your carrier. The national emergency number is 000, which connects callers to police, fire, or ambulance services. The code 112 functions as a secondary emergency number on mobile handsets, though it does not work from landlines and is not universally supported across all technologies.

Who are the major landline providers in Australia, and how can you contact them?

The era of traditional copper telephone lines is drawing to a close in Australia, with home phone services progressively migrated to the National Broadband Network (NBN). Rather than running over dedicated copper infrastructure, modern home phone services use Voice over Internet Protocol (VoIP) technology delivered through your NBN connection. This means your handset plugs into a dedicated port on your modem or NBN connection box instead of the telephone wall sockets found throughout older Australian homes.

The vast majority of NBN retail providers offer internet and home phone as a combined package. Connecting a compatible handset to your modem carries no separate hardware fee, though call charges are usually handled either on a pay-as-you-go basis or through a bundled call pack. As of 2025, unlimited standard national call packs — covering local, national, and mobile numbers — typically cost around AUD $10 per month when added to an NBN plan, though pricing varies between providers and changes over time, so always verify current rates on each provider’s website.

Under the Universal Service Obligation (USO), Telstra carries a legislated responsibility to provide a standard telephone service to every premises across Australia upon request and within reasonable timeframes. This obligation makes Telstra the essential provider of last resort, particularly for properties in rural and remote locations where other providers may not operate.

More than 100 accredited retail service providers currently operate on the NBN, and the number continues to rise. The nbn co website provides a complete, searchable directory of all accredited providers. For objective performance data, the Australian Competition and Consumer Commission (ACCC) publishes its Measuring Broadband Australia report on a regular basis, offering real-world speed and performance comparisons across providers.

Aussie Broadband has developed a strong reputation for prioritising customer service, operating an entirely Australia-based support team and winning Finder’s Broadband Customer Satisfaction Award for the third time in 2025. Other providers such as TPG, Dodo, Exetel, and Optus operate hybrid support models, with front-line staff located in Australia and overflow support provided by teams in South and South-East Asia.

Who are the major mobile phone providers in Australia, and how can you contact them?

Three network operators underpin Australia’s entire mobile ecosystem: Telstra, Optus, and Vodafone. Every mobile plan available in the country — whether sold directly by one of these companies or through a smaller reseller — runs on one of these three networks. Mobile Virtual Network Operators (MVNOs), including well-known names such as Boost Mobile, Amaysim, Woolworths Mobile, and Lebara, purchase wholesale capacity from the major networks and typically offer more competitively priced plans, though some MVNOs may not have access to the full extent of their host network’s coverage area.

Telstra’s network reaches 99.7% of the Australian population, giving it the broadest geographical footprint in the country. It also operates the most extensive 5G network, covering 89% of the population. In many rural and outback communities, Telstra is the sole provider offering any signal at all.

The Optus network extends to approximately 98.5% of the population. While it does not match Telstra in remote and rural areas, Optus offers reliable coverage across metropolitan and suburban regions and has been steadily expanding its 5G infrastructure.

Vodafone has significantly extended its reach through a regional network-sharing arrangement with Optus. Under this agreement, Vodafone gains access to more than two thousand Optus tower sites across regional Australia, pushing its total population coverage to 98.4%.

If your life in Australia will take you beyond the major cities — into regional Queensland, the Pilbara, or outback South Australia, for example — Telstra or an MVNO with unrestricted access to Telstra’s full network is strongly recommended. Boost Mobile, which Telstra acquired in December 2024, is presently the only MVNO granted full Telstra network access. Before signing up with any provider, use the coverage checker on their website to verify signal availability at your specific location. The Australian Communications and Media Authority (ACMA), as the national telecommunications regulator, is also a useful reference for network standards and spectrum information.

How do I get a landline connected in Australia?

In contemporary Australia, setting up a home phone line is almost always part of the process of arranging an NBN internet connection with a voice add-on, rather than ordering a standalone traditional copper line. The steps below outline the standard process for a new residential connection.

1. Check NBN availability at your address. Visit nbn.com.au and enter your address to confirm whether the NBN is available and which connection technology (fibre, fixed wireless, or satellite) serves your property. Most urban and suburban addresses in Australia are already connected.
2. Choose a retail service provider (RSP). You cannot sign up directly with NBN Co — you must choose a retail provider such as Telstra, Optus, iiNet, Aussie Broadband, or one of the other accredited RSPs. Compare plans that include a home phone (voice) add-on. Unlimited standard national call packs typically cost around AUD $10 per month as an add-on (as of 2025).
3. Gather required documents. Providers will ask for proof of identity (a passport, national ID card, or driver’s licence) and your Australian address. Renters and property owners follow the same sign-up process, though renters should confirm with their landlord that installing NBN equipment (such as a connection box) is permitted.
4. Place your order online, by phone, or in-store. Most providers allow fully online sign-up. You will typically need to agree to a credit check for postpaid plans. No upfront deposit is standard for most residential plans, though modem costs may apply.
5. Arrange installation if required. Existing fixed-line services will be disconnected at a future date, and occupiers will not be able to make phone calls or access the internet over the fixed-line network unless NBN-supplied equipment is installed at the property. If a technician visit is needed, your provider will schedule an appointment; standard installations are generally completed within 2–15 business days, though timeframes differ by location and provider. Confirm current lead times with your chosen provider before ordering.
6. Connect your handset. Your home phone plugs into a dedicated port on your modem or NBN connection box rather than a traditional telephone wall socket. A standard cordless or corded handset is all you need, and these are widely available from electronics retailers and supermarkets throughout Australia.
7. Port your existing number (if applicable). If you already have an Australian landline number, you are entitled to retain it when switching to a new provider. Request that your new provider manages the porting process; number transfers typically complete within a few business days.

If your property is in a rural or remote location not yet served by the NBN, Telstra is legally required under the Universal Service Obligation to supply a standard telephone service to every Australian premises upon request within a reasonable timeframe. Contact Telstra directly on 132 200 to discuss your options. Should your connection be unreasonably delayed, or if a dispute arises, the Telecommunications Industry Ombudsman (TIO) offers a free, independent complaints resolution service.

How do I get a mobile phone SIM card or contract in Australia?

Australia’s mobile market offers both prepaid and postpaid plan structures. Prepaid plans give users tight control over their spending and require no credit commitment, though many operate on 28-day rather than monthly billing cycles. Postpaid plans consolidate charges into a single monthly bill and remove the need to monitor your remaining balance, but typically involve a credit assessment during sign-up.

For people who have recently arrived in Australia — whether on a working holiday visa, a skilled migration pathway, or as a new permanent resident — a prepaid SIM is usually the most accessible and hassle-free starting point. These SIMs are sold across supermarkets (Coles, Woolworths), convenience chains (7-Eleven), electronics retailers (JB Hi-Fi, Harvey Norman), and directly through carrier stores and websites. You can walk in, purchase, and activate a SIM on the same day, and no prior Australian credit history is required.

Registering a prepaid SIM requires identity verification under Australian law. You will be asked to produce at least one government-issued identity document, such as a passport, national identity card, or driver’s licence. This obligation stems from Australia’s Telecommunications (Service Provider — Identity Checks for Mobile Phone Services) Determination. Importantly, while identity verification is mandatory, prepaid SIM registration does not require permanent residency or an established local credit history — unlike postpaid contract sign-ups.

Postpaid plans require a verified Australian residential address, identity documentation, and in most cases a credit check. New arrivals who have not yet built up an Australian credit history may find it more practical to begin with a no-lock-in, month-to-month postpaid SIM-only plan rather than applying for a 12- or 24-month device repayment arrangement, which generally demands a more established credit profile. This situation mirrors the experience of temporary residents in countries like France or Germany, where postpaid contracts are similarly subject to credit restrictions for those without a domestic financial track record.

Mobile Virtual Network Operators (MVNOs) are companies that market mobile services using capacity leased from one of the three major networks. Because their wholesale arrangements typically come at lower cost, MVNOs can offer more affordable plan pricing. The trade-off is that some MVNOs do not have access to the complete network coverage footprint or the highest network speeds, particularly in rural areas or for 5G. If regional coverage is important to you, always verify which underlying network an MVNO uses before committing.

eSIM technology is widely supported across Australia. All three major networks and a growing number of MVNOs now offer eSIM activation, enabling compatible smartphones to be configured entirely online — no waiting for a physical card to arrive in the post. This makes eSIMs particularly convenient for new arrivals who want mobile connectivity from the moment they land.

How do I pay my telephone bill in Australia?

Australian telecoms providers give customers several ways to pay their bills for both landline and mobile services. Widely available options include direct debit from a bank account, credit or debit card payments through the provider’s website or mobile app, BPAY via online banking, and in-person payment at selected retail stores or Australia Post outlets.

BPAY is a payment system unique to Australia that is well worth understanding as a newcomer. It operates through your bank’s internet banking platform: you simply enter the biller code and customer reference number printed on your invoice. Virtually all Australian banks support BPAY as a built-in feature, and it is the standard method for settling utility and telecommunications bills throughout the country. Functionally, it resembles a direct bank transfer, but payments are routed and cleared through a centralised national system.

Postpaid bills for both landline and mobile services are typically generated monthly. Most providers offer direct debit setup to ensure payments are never missed. Eligible concession card holders may qualify for a monthly reduction on their plan costs and an exemption from late payment fees. For all other customers, policies on late fees and service disconnection vary by provider and are detailed in each provider’s Critical Information Summary (CIS) — a document that providers are legally required to make prominently available on their websites.

Prepaid mobile recharges can be completed through the provider’s app or website, at convenience stores and supermarkets, or via automatic recharge, where a nominated payment card is charged automatically once your data or balance is depleted. It is important to understand your plan’s recharge cycle: while many plans renew every 30 days, some prepaid options expire every 28 days or even sooner. Knowing your plan’s exact expiry schedule will help you avoid any unexpected service interruptions.

If you believe a bill is incorrect or have a dispute with your provider, begin by raising the matter directly with the company. If the issue remains unresolved, you can escalate your complaint at no cost to the Telecommunications Industry Ombudsman (TIO), an independent body empowered to investigate consumer disputes and direct providers to take corrective action where appropriate.

Are there any practical tips for using phones in Australia as a newcomer?

International roaming: All three major networks support international roaming, generally as a daily or monthly add-on to your existing plan. Vodafone has traditionally offered competitive roaming inclusions. Provided your handset is unlocked from any previous carrier and supports the frequency bands used in Australia, it will operate normally here. Australia’s mobile networks use standard 4G LTE bands and 5G sub-6GHz frequencies compatible with most modern smartphones sold around the world.

Number porting: Since the introduction of mobile number portability, your phone number belongs to you rather than your network. You can transfer your Australian mobile number to a new provider simply by asking your new carrier to handle the process — this typically takes one to two business days. The process is broadly similar to number porting in other countries such as the UK, though Australian ports can occasionally involve slightly more manual processing steps; your new provider will give you an expected timeline. Note that overseas phone numbers cannot be ported to an Australian carrier — you will need to register a new Australian number upon arrival.

eSIMs: Telstra, Optus, Vodafone, and a growing number of MVNOs all offer eSIM activation. Setting up an eSIM is entirely digital — no physical card is required — and can be completed before you board your flight to Australia. Dual-SIM capable phones allow you to run both an Australian eSIM and your home country SIM simultaneously, making it easy to stay reachable on both numbers while you transition to life in Australia.

Urban vs regional coverage: Mobile coverage in Australia’s major cities is generally excellent across all three networks. However, coverage quality can drop noticeably as you move into rural and regional areas. In these locations, Telstra consistently provides the strongest signal, followed by Optus, with Vodafone having the most limited regional presence. Anyone planning to spend time outside city centres should factor network coverage into their choice of provider.

Emergency calls: Australia’s national emergency number is 000, which connects you to police, fire, and ambulance services. Mobile handsets sold through Australian retail channels are required to treat 000 in the same way as 112 — bypassing screen locks, using any available carrier signal, and applying priority routing. If your phone was purchased outside Australia’s normal retail distribution, verify that 000 functions correctly on your device before you need it in a real emergency.

Phone etiquette: Australians take a generally relaxed approach to mobile phone use in everyday public life, but using a phone during meetings, meals, or direct conversations is considered impolite. Placing loud speakerphone calls in shared public spaces is similarly frowned upon. When contacting businesses by phone, standard business hours of 9 AM to 5 PM apply in most states, though opening hours can vary across different regions and industries.

Regulatory oversight: The Australian Communications and Media Authority (ACMA) serves as Australia’s primary regulator for telecommunications and broadcasting. The Australian Competition and Consumer Commission (ACCC) oversees competition law and consumer protection in the telecoms sector, and publishes regular reports on broadband pricing and real-world performance. Both organisations are authoritative and up-to-date sources of information for consumers.

Frequently asked questions

Can I keep my foreign phone number when I move to Australia?

No — it is not possible to transfer a foreign number to an Australian carrier. You will need to register a new Australian mobile number when you arrive. That said, if your phone supports dual SIM functionality, you can continue using your overseas SIM alongside your new Australian one, allowing you to receive incoming calls on your old number while using the Australian number for local communications.

Do I need a local address to get a SIM card in Australia?

For a prepaid SIM, the key requirement is identity verification using a valid passport or government-issued ID; a permanent Australian address is not necessarily required before you can make a purchase. For a postpaid or contract plan, however, you will need to provide an Australian residential address and will generally be subject to a credit check before your application is approved.

Can I sign up for a postpaid mobile contract as a temporary resident or tourist?

Technically yes, though in practice many newcomers who lack an established Australian credit history find it simpler to begin with a prepaid plan or a flexible, no-lock-in month-to-month postpaid SIM-only option. Longer-term device repayment plans generally require a satisfactory credit assessment, which can be challenging to pass when you have no previous financial history in Australia.

What is the NBN and how does it affect my home phone?

The National Broadband Network (NBN) is the national wholesale broadband infrastructure that now underpins most of Australia’s fixed-line internet and home phone services. Rather than running over a dedicated copper telephone line, modern home phone services use VoIP technology delivered over your NBN connection. When you add a voice option to an NBN plan, your handset connects to a port on your modem instead of a traditional telephone wall socket — though you still receive a regular phone number and can make and receive calls as normal.

Which mobile network has the best coverage in rural areas?

Telstra covers 99.7% of the Australian population, making it the most extensive network in the country by a significant margin. For anyone living in or travelling to areas outside major population centres, Telstra — or an MVNO such as Boost Mobile that operates with full access to the Telstra network — is typically the most dependable choice. Always consult the official coverage map on a provider’s website before choosing a plan for a rural address.

How do I make a complaint about my phone or internet provider in Australia?

Your first step should be to contact your provider directly and formally raise the issue. If the complaint is not resolved to your satisfaction within a reasonable period, you can escalate the matter for free to the Telecommunications Industry Ombudsman (TIO). The TIO operates as an independent body with the authority to investigate consumer disputes and, where warranted, require providers to take corrective action at no cost to the customer.

Are eSIMs widely available in Australia?

Yes. All three major networks — Telstra, Optus, and Vodafone — support eSIM activation, and many MVNOs now offer the same capability. For new arrivals, eSIMs offer a significant practical advantage: the entire setup process can be completed online, either before departure or immediately on arrival, with no need to wait for a physical SIM card. They also allow dual-SIM operation, so you can run both a home-country SIM and an Australian SIM on the same compatible device. Always confirm your handset model supports eSIM before purchasing a plan.

What is the difference between a 28-day and a monthly prepaid plan?

A monthly plan renews every 30 days, while a 28-day plan renews on a shorter cycle — meaning you will complete 13 billing periods in a calendar year instead of 12. This effectively raises the true annual cost of a 28-day plan compared to a nominally similar monthly one, even if the per-cycle price appears equivalent. Always confirm the exact billing cycle length before committing to a prepaid plan to ensure there are no unexpected costs.
