How to buy the best prepaid SIM card in Australia

Planning a trip to Australia involves more than just booking flights and choosing accommodation. One of the most important parts of your preparation is ensuring you have reliable, affordable mobile data. But, if you’re travelling from the UK, navigating international roaming fees and local Australian options can be confusing.

In this guide, we break down your options and explain why an eSIM for Australia is a convenient and cost-effective way to stay connected.

Why reliable mobile data is essential for your Australia trip

Beyond the obvious need to share your holiday snaps, connectivity is vital for several reasons:

• Navigation: using apps like Google Maps or other digital maps to navigate complex streets or find hidden spots
• Transport: booking local transport, including via apps like Uber
• Safety: having access to emergency numbers and resources the moment you need them

Without an Australian SIM card, you rely entirely on hotel or café Wi-Fi, which can be patchy, slow, and, in some cases, unsecure.

Can I use my UK SIM card in Australia?

The answer is yes, but it's almost always the most expensive option. Since Brexit, many UK mobile networks (like Vodafone, EE, and Three) have re-introduced or increased daily charges and out-of-bundle rates for roaming outside Europe.

The high cost of roaming with a UK SIM card

Australia is one of the most expensive roaming zones for most UK providers. While specific rates vary, you could face charges relating to:

• Daily passes: paying a daily fee (often between £6–8) to unlock your home plan's data allowance. These can quickly add up on a 2-week trip.
• Pay-as-you-go (PAYG) rates: if you don't buy a pass, the charges are often expensive. Data can cost upwards of £1 per MB (megabyte), meaning a few minutes of video streaming or a simple map download could cost a lot.
• Hidden use: even background apps updating or receiving a simple text message can trigger minimum daily charges or start accumulating fees you won't see until your bill arrives.

If you're travelling on a budget or plan to stay in the country for more than a few days, using your UK mobile plan isn't a good idea. It's usually best to switch off data roaming as soon as you land in Australia to avoid bill shock.

Local Australia SIM cards: your traditional options

Australia has 3 main mobile network operators: Telstra, Optus, and Vodafone.

These operators offer dedicated Australia prepaid SIM card plans, which provide a fixed amount of high-speed data and sometimes some local calling credit for a set number of days.

Leading Australian mobile operators and plans

The main players are known for great coverage, but there are differences between them, particularly for those planning to leave the East Coast. Here's what they each typically offer:

• Telstra is known for having consistent coverage, making it the most reliable choice for customers heading to remote areas, including the outback or on long road trips. Their prepaid tourist plans are often priced slightly higher but offer good reach across the country.
• Optus provides strong coverage in metropolitan and most regional areas, offering competitive pricing and generous data allowances. They're a good choice for customers primarily staying in large cities like Sydney, Melbourne, Adelaide, or Perth.
• Vodafone AU offers more affordable plans and is great for budget-conscious customers staying exclusively in the major urban centres where their network is strongest. Coverage can be significantly weaker once you venture into rural or outback Australia.

Where can I buy an Australian SIM card?

• Airports: the most convenient spot is usually immediately after baggage claim at major airports like Sydney (SYD), Melbourne (MEL), or Brisbane (BNE). Options available in the airport can sometimes be slightly more expensive than in the city.
• Convenience stores and supermarkets: you can often purchase an Australian SIM at supermarket chains like Woolworths or Coles, as well as convenience stores like 7-Eleven. These options are often cheaper but require you to register and activate the SIM yourself, which requires a Wi-Fi connection.
• Official stores: visiting an official Telstra, Optus, or Vodafone shop in a shopping mall ensures you get the best advice and full activation support, but this takes time out of your holiday.

If you do choose the traditional route, be prepared for some bureaucracy and a brief delay.

Important: Australian law requires all mobile SIM cards to be registered. When buying a physical SIM, you need to show your passport or other ID to the vendor, who will verify your details to complete the registration process.

The modern alternative: why an Australia eSIM is the smarter choice

While buying a local prepaid SIM card is better than relying on expensive UK roaming, it still involves hassle and takes time. This is where embedded SIMs (eSIMs) offer a solution, and we're leading the charge for travellers.

An eSIM is a digital SIM profile embedded in your phone's hardware. Instead of swapping out tiny pieces of plastic, you simply install a data plan digitally using a QR code or an activation code.

The advantage of Revolut eSIMs

We offer a range of regional and global eSIM plans, including a dedicated Australian eSIM option that can be purchased and activated in-app.

By choosing a digital solution, you can land in Australia with your connectivity already sorted. You can search for directions, book a taxi, and contact your accommodation the moment you step off the plane.

Staying connected across the region

If your holiday involves more than just Australia, perhaps a hop to New Zealand or the Pacific Islands, buying multiple physical SIM cards is inconvenient. Our regional plans, including our Asia Pacific eSIM, offer coverage across multiple countries, ensuring you remain connected throughout your entire multi-stop itinerary without needing a new SIM at every border.

To find out more about which plans suit your trip, just check in-app. We offer plans for Australia and 100+ other countries globally.

More ways we make travelling to Australia easier

Managing your spending in Australian dollars (AUD) is just as important as staying connected. We have various offerings designed to simplify your travel finances, making your trip stress-free.

Spending seamlessly with your Revolut card

Exchanging currency by ordering cash from a high street bank or a bureau de change can often mean poor exchange rates. But, with a multi-currency account at Revolut, you can manage your spending in AUD at competitive rates.

Our multi-currency account allows you to hold, exchange, and spend in dozens of currencies, including AUD. When you use your Revolut card in Australia, we automatically convert your money using competitive rates, allowing you to spend like a local without worrying about excessive fees. You can easily keep track of your transactions in real-time in-app, helping you stick to your holiday budget.

Protecting your trip with Revolut travel insurance

For many travellers, especially those heading to adventure spots or remote islands, having comprehensive travel insurance is non-negotiable.

Depending on your Revolut plan, you may have travel insurance benefits included, ranging from medical emergencies to trip cancellations and flight delays. Knowing you have reliable coverage means you can enjoy Australia's stunning beaches, vast outback, and adventurous excursions with greater peace of mind. Check your specific plan details in-app to see what's included.

Final travel tips for Australia

Now you’ve got your SIM sorted, here are a few extra tips to ensure a smooth, worry-free trip:

1. Cash and cards: Australia is card-centric, but cash (in AUD) is still useful for small markets, remote petrol stations, or some local services. You can withdraw cash from ATMs using your Revolut card.⁴
2. The power of apps: download ride-sharing apps like Uber or Ola and check local safety apps, especially if you plan to hike or swim in unpatrolled areas.
3. Local culture: Australians are generally laid-back, and you’ll hear 'mate' used frequently. Tipping isn't expected, though appreciated for excellent service. Sun safety is critical — always wear a hat and sunscreen, and cover up during peak UV times.
4. Essential adaptors: don't forget Australia uses Type I power outlets (3 flat pins), which are different from UK plugs, so make sure you bring a travel adaptor.

No withdrawal fees charged by Revolut within your plan's rolling monthly limit. Fair-usage fees and third-party ATM fees may apply.
