Summary
Australia has three main mobile networks — Telstra, Optus and Vodafone — plus a wide range of budget MVNOs (virtual operators) that run on the same towers at lower prices; the right choice depends on where you live and whether you need regional coverage. For many, getting a SIM card Australia migrants can rely on is essential for staying connected.
Telstra has the widest coverage — reaching 98.8% of Australia’s landmass and the only reliable option in regional and remote areas; Optus and Vodafone cover 99% of the population (who are concentrated in cities) and are significantly cheaper
For cheap international calls home, Lebara (on Vodafone’s network) offers unlimited standard international minutes to 35+ countries on its current prepaid plans — the most popular choice among migrants who call family overseas regularly. Check lebara.com.au for current pricing and country list
Getting a SIM card is one of the first things you should do when you arrive in Australia. You need a phone number to receive calls from employers, set up bank accounts, receive verification codes, and navigate a new city with maps. This guide covers your options and helps you choose the right plan from day one.
Australia’s three main networks
Australia has three mobile network operators:
Telstra — Australia’s largest network by geographic coverage. Covers 98.8% of the landmass. The only reliable option if you will work or travel in regional Australia, the outback, or remote areas. Premium pricing — but no other network comes close outside major cities.
Optus — Second largest network. Covers 99.1% of the population with 4G. A solid choice for migrants living and working in major cities. Generally cheaper than Telstra with comparable urban performance.
Vodafone — Now majority-owned by TPG, which has a network sharing agreement with Optus. Covers 99% of the population with 4G — essentially the same urban coverage as Optus. Generally the most affordable of the three major networks.
Key rule: In Australian cities, all three networks perform similarly well. Outside major cities, Telstra is the only reliable choice.
MVNOs — same network, lower price
Most migrants do not need to buy directly from Telstra, Optus or Vodafone. MVNOs (Mobile Virtual Network Operators) use the same network infrastructure at 20-50% lower prices.
| MVNO | Network used | Best for |
|---|---|---|
| Boost Mobile | Telstra (full network) | Best Telstra-quality at slightly lower price |
| Woolworths Mobile | Telstra | Telstra coverage, simple top-up at Woolworths |
| Aldi Mobile | Telstra | Very cheap Telstra-based plans |
| Lebara | Vodafone | Best for international calls — unlimited mins to 35+ countries |
| Lycamobile | Vodafone | International calls to specific countries |
| Amaysim | Optus | Cheap Optus-based plans |
| Circles.Life | Optus | Data-heavy users, 24/7 online support |
Important: Telstra MVNOs (Boost, Woolworths, Aldi) access the Telstra “Wholesale” network — slightly less 4G coverage than buying directly from Telstra. For full Telstra coverage, use Boost Mobile or buy direct from Telstra.
Which SIM is best for you?
You live in a major city (Sydney, Melbourne, Brisbane, Perth, Adelaide)
All three networks work well in cities. Lebara (Vodafone) is the most popular choice for migrants who call family overseas regularly — current plans include unlimited standard minutes to 35+ countries. Check lebara.com.au for current pricing. Aldi Mobile (Telstra) at AUD $19/15GB is the cheapest option with Telstra-quality coverage.
You live or work in regional Australia
Telstra or Boost Mobile (Telstra full network). Do not compromise on this — other networks can have no signal in regional areas.
You want the cheapest possible plan
Aldi Mobile — from AUD $13.90/4GB/28 days on Telstra’s network. Available at any Aldi store.
You call family overseas often
Lebara — current plans include unlimited standard international minutes to 35+ countries including India, Philippines, Nepal, Vietnam, Bangladesh, UK and many others. Check lebara.com.au for current pricing and country list.
You want maximum data
Circles.Life or Amaysim (Optus) offer high-data plans at competitive prices for users who stream a lot.
Where to buy your SIM card
Airports: Telstra, Optus and Vodafone have stores at Sydney and Melbourne airports. Other airports (Brisbane, Perth, Adelaide, Darwin) usually stock Optus and Vodafone but not always Telstra. Airport SIMs are often more expensive than in-city prices — buy in-city if you can wait.
Supermarkets: Aldi Mobile SIMs at Aldi stores. Woolworths Mobile at Woolworths. Lebara at 7-Eleven, Woolworths and Coles.
Convenience stores: Lebara and Lycamobile at 7-Eleven and most newsagents.
Official stores: Telstra, Optus and Vodafone retail stores in all major cities — staff will activate your SIM before you leave.
Online / eSIM: Order before you arrive. Most providers offer eSIMs for compatible phones — activate on the plane and arrive connected. Telstra, Optus, Vodafone, Boost and Lebara all offer eSIMs.
What you need to buy a SIM card
Australian law requires identity verification to purchase a SIM card. You need:
- Your passport — accepted by all providers as primary ID
- A valid Australian address (your accommodation, hostel or employer address is fine)
You cannot activate a SIM card anonymously in Australia — this is a legal requirement under the Telecommunications (Interception and Access) Act.
Prepaid vs postpaid — what’s the difference?
Prepaid: You pay before you use. Load a plan onto your SIM in advance — when the plan period expires (typically 28 days), top up to continue. No contract, no credit check, no bills. You can switch providers at any time. The right choice for new migrants on arrival.
Postpaid: You pay after you use, on a monthly bill. Requires a credit check, a permanent Australian address and an Australian bank account. Better value for long-term residents — plans typically include more data for the same price — but not accessible on day one.
For new migrants: Start prepaid on arrival, switch to postpaid once you have a bank account, permanent address and a month or two of local credit history. Most providers let you keep your number when you switch.
Making international calls cheaply
Lebara is the most popular choice among migrants for international calls — current plans include unlimited standard minutes to 35+ countries. Check lebara.com.au for current pricing.
WhatsApp, Viber, FaceTime and Messenger are free over Wi-Fi or data — most migrant communities use these as the primary way to stay in touch with family.
Calling cards are less common than they used to be but can still be found at newsagents for specific country calls.
OrbitRemit rate alerts: If you want to be notified when the AUD exchange rate is favourable before sending money home, use the free rate alert feature in the OrbitRemit app — no calls required, push notification when your target rate is hit.
