The Quick Answer

If you need mobile data in Australia without a physical SIM card:

  • Best for visitors to Australia: Airalo Australia eSIM at A$6.50 for 1GB/7 days up to A$33 for 10GB/30 days. Activates instantly, works on the Optus or Telstra network depending on the plan, and you can buy it before you land. Use code ONLYCNEW for 15 percent off your first order or ONLYC for 10 percent off any order.
  • Best for Australians travelling abroad: Airalo regional or global eSIMs covering Indonesia, Thailand, Japan, the United Kingdom, France, Germany, and 200+ countries. Far cheaper than Telstra or Optus roaming rates, which charge A$5 to A$10 per day.
  • Best local alternative: Telstra prepaid eSIM at A$30 for 40GB/28 days. If you want the best Australian network coverage including regional and outback areas, Telstra is unmatched. Available as an eSIM through the My Telstra app.
  • Best budget local: Optus prepaid eSIM at A$30 for 50GB/28 days. More data than Telstra for the same price, with strong coverage in capital cities and suburban areas. Weaker in regional Australia.

Why eSIM Instead of a Physical SIM

Every major Australian carrier now supports eSIM activation, and most phones sold in Australia since 2019 are eSIM-compatible. The advantages are straightforward:

  • No queue at the airport. Sydney, Melbourne, Brisbane, and Perth airports all have mobile counters, but the queues after international flights can stretch 20 to 30 minutes. An eSIM activates from your phone in under 5 minutes.
  • Keep your home number active. An eSIM runs alongside your existing physical SIM. Visitors can keep their home number for calls and texts while using the eSIM for Australian data. Australians travelling abroad can add a travel eSIM without swapping out their Telstra or Optus SIM.
  • Instant top-up. Running low on data at Uluru or on the Great Ocean Road? Top up through the app without finding a retail store.
  • No tiny SIM card to lose. Anyone who has dropped a nano-SIM into a rental car seat or hotel carpet knows this pain.

Airalo - Our Top Pick for Travellers

Airalo is the largest eSIM marketplace with coverage in over 200 countries. For Australia specifically, they offer data-only eSIMs that work on the Optus network in most plans.

Australia Plans

| Plan | Data | Validity | Price (USD) | Approx AUD | |---|---|---|---|---| | Discover | 1 GB | 7 days | $4.50 | A$6.50 | | Explorer | 2 GB | 15 days | $8.00 | A$11.50 | | Traveller | 3 GB | 30 days | $11.00 | A$16.00 | | Navigator | 5 GB | 30 days | $16.00 | A$23.00 | | Pioneer | 10 GB | 30 days | $23.00 | A$33.00 |

All Airalo plans are data-only, meaning no Australian phone number for local calls. Use WhatsApp, FaceTime, or Signal for calls and messages. This is fine for most travellers but a limitation if you need to call local businesses or receive SMS verifications from Australian services.

How to Activate

1. Download the Airalo app from the App Store or Google Play 2. Search for "Australia" and select your preferred plan 3. Apply code ONLYCNEW at checkout for 15 percent off (first order) or ONLYC for 10 percent off 4. Install the eSIM profile through the QR code or direct installation 5. Enable data roaming in your phone settings 6. The eSIM activates when you connect to an Australian network

You can buy and install the eSIM before arriving in Australia. It will not activate or start counting days until you connect to a local network.

Airalo for Australians Travelling Abroad

This is where Airalo saves Australians serious money. Telstra charges A$5 per day for international roaming (data, calls, texts in selected countries). Optus charges A$5 to A$10 per day depending on the destination. Over a two-week holiday in Bali or Japan, that adds up to A$70 to A$140.

An Airalo regional eSIM for Indonesia, Thailand, Japan, South Korea, Vietnam, and Singapore costs A$12 to A$35 for 1 to 10GB. For trips to the United Kingdom, France, Germany, Italy, and Spain, a regional eSIM costs A$7 to A$55 for 1 to 20GB.

The savings on a single overseas trip typically pay for a year of eSIM data. Use code ONLYC for 10 percent off on any plan.

Local Carrier eSIMs - When to Choose Them Instead

Telstra Prepaid eSIM

Best for: Regional and outback travel, longest stays, anyone who needs the most reliable network coverage.

Telstra has the widest network coverage in Australia, reaching areas where Optus and Vodafone have no signal. If you are driving the Stuart Highway, visiting Kakadu, camping in the Kimberley, or road-tripping through Central Australia, Telstra is the only carrier that reliably works.

Plans:

  • A$30 for 40GB/28 days
  • A$40 for 65GB/28 days
  • A$55 for 100GB/28 days
All plans include unlimited calls and texts within Australia plus international calls to selected countries. Activate through the My Telstra app with ID verification (passport for visitors, Australian ID for locals). The process takes about 10 minutes.

Optus Prepaid eSIM

Best for: City and suburban travellers on a budget who want more data for less money.

Optus offers more data than Telstra at each price point and has strong coverage in all capital cities, major towns, and suburban areas. Coverage drops off faster than Telstra in regional areas.

Plans:

  • A$30 for 50GB/28 days
  • A$40 for 80GB/28 days
  • A$50 for 120GB/28 days
Activate through the My Optus app. International visitors need to verify identity with a passport. Optus also offers 5G access on compatible phones in Sydney, Melbourne, Brisbane, Perth, and Adelaide at no extra charge.

Vodafone Prepaid eSIM

Best for: Short stays in major cities.

Vodafone has the smallest network of the three carriers but competitive pricing. Stick to capital cities and major towns.

Plans:

  • A$30 for 40GB/28 days
  • A$40 for 60GB/28 days

Which Phones Support eSIM in Australia
