Shopping for an eSIM for Australia gets awkward the moment your trip runs past a month. On 22 September 2026 our catalog had 21 Australia-only plans, and not one of them lasted longer than 30 days. The cheapest 10 GB plan for 30 days cost $9.99. The longest plan that covers Australia at all lasts a year, but it comes bundled with other countries and costs more per gigabyte.
That gap matters in Australia more than most places, because trips there run long. The standard tourist visa lets you stay up to three months at a time, and a road trip up the east coast or into the Red Centre easily fills several weeks. This guide prices every trip length from one week to one year using the plans in our catalog, and covers what a data plan can and cannot do once you leave the coverage map. The full list is on our Australia plans page. Plan details change, so treat the live listing on each product page as the source of truth before you buy.
How many eSIM plans cover Australia?
Our catalog had 1,674 published plans on 22 September 2026, and 114 of them list Australia in their coverage. Fifty-one of those are top-up packages, which add data to an eSIM you already installed, so 63 are available as a first purchase.
| Group | Fresh plans | Top-ups | What it means for you |
|---|---|---|---|
| Australia only | 21 | 7 | Four suppliers, validity from 3 to 30 days |
| Australia plus other countries | 42 | 44 | From Australia and New Zealand packs to world plans |
| Total covering Australia | 63 | 51 | Every plan in our catalog that lists AU |
Every one of the 42 multi-country plans also covers New Zealand. Ten of them cover ten countries or fewer, and nine of those ten are two-country Australia and New Zealand packs. Another ten cover 11 to 30 countries, all of them Asia or Asia-Pacific plans, and 22 cover more than 50.
The 21 Australia-only plans come from four suppliers: nine from Airalo, five from TSimTech, four from RoamVault and three from eSIMGo. By validity, six last a week or less, four last 10 to 15 days and eleven last 30 days.
What does an Australia eSIM cost for 7, 15 and 30 days?
For trips up to a month, the Australia-only plans are the ones to look at first. Here is the cheapest option at each common trip length.
| Trip length | Cheapest plan covering Australia | Price | Cost per day |
|---|---|---|---|
| 7 days | Australia 1 GB | $4.99 | $0.71 |
| 7 days | Australia 3 GB | $5.49 | $0.78 |
| 14 to 15 days | Australia and NZ 1 GB, 14 days | $4.49 | $0.32 |
| 15 days | Australia 5 GB | $7.49 | $0.50 |
| 30 days | Australia 5 GB | $6.99 | $0.23 |
| 30 days | Australia 10 GB | $9.99 | $0.33 |
| 30 days | Australia 20 GB | $17.99 | $0.60 |
| 30 days | Australia 50 GB | $37.99 | $1.27 |
One result stands out. The cheapest 5 GB plan valid for 30 days costs $6.99, which is less than the 5 GB plan valid for 15 days at $7.49. Longer validity does not always cost more, so on a trip of two to three weeks it is worth checking the 30-day plans before settling on a shorter one.
Australia-only or Australia and New Zealand?
Where both kinds of plan exist at the same size and validity, the Australia-only plan was cheaper at four of five tiers.
| Data and validity | Cheapest Australia-only | Cheapest multi-country with Australia | Cheaper option |
|---|---|---|---|
| 1 GB, 7 days | $4.99 | $6.49 (Asia, 14 countries) | Australia-only |
| 3 GB, 30 days | $7.99 | $7.49 (Australia and NZ) | Multi-country |
| 5 GB, 30 days | $6.99 | $10.99 (Australia and NZ) | Australia-only |
| 10 GB, 30 days | $9.99 | $18.99 (Australia and NZ) | Australia-only |
| 20 GB, 30 days | $17.99 | $31.99 (Australia and NZ) | Australia-only |
At 10 GB the two-country pack costs $9.00 more. That is the reverse of Europe, where a regional plan often undercuts the single-country one. If your trip includes New Zealand, compare two Australia-only and New Zealand-only plans against one combined pack before buying. The combined pack wins on convenience, since one eSIM works in both countries, but it rarely wins on price at the larger sizes.
Staying longer than 30 days: stack monthly plans or buy one long plan?
This is where Australia differs from a week in Tokyo or Paris. No Australia-only plan in our catalog runs past 30 days, so a longer stay means one of two things: buying a new 30-day plan each month, or buying a single multi-country plan with long validity.
| Stay | Stacking the $9.99 10 GB plan | Cheapest single plan that lasts the whole stay |
|---|---|---|
| 60 days | $19.98 for 20 GB | $31.99 for 5 GB over 60 days (129 countries) |
| 90 days | $29.97 for 30 GB | $50.99 for 20 GB over 365 days (80 countries) |
| 180 days | $59.94 for 60 GB | $50.99 for 20 GB over 365 days (80 countries) |
| 365 days | $119.88 for 120 GB | $50.99 for 20 GB over 365 days (80 countries) |
Up to about five months, stacking is cheaper outright. From six months on, the $50.99 yearly plan costs less in total, but it gives you a third of the data or less. Per gigabyte, stacking wins at every length: $1.00 per GB, against $1.60 per GB for the best-value yearly plan, a $55.99 plan with 35 GB covering Australia, New Zealand, the United States, Canada, the United Kingdom and Hong Kong. That works out to under 3 GB a month. The long plans only make sense if you use little data and would rather not install a new eSIM every month.
Three details decide how stacking works in practice:
- Buy each plan shortly before you need it. The Australia-only listings say an eSIM expires if it is not activated within two months of purchase. Buying three months of plans on day one would leave the third at risk.
- The cheapest plans cannot be topped up. Only the five Airalo plans among the 21 Australia-only plans accept top-ups. The RoamVault and TSimTech plans that lead on price need a fresh eSIM each time, which means a new QR code and a new line in your phone’s settings. More on how refills work in Can You Top Up a Travel eSIM?
- Some yearly plans start on installation. All seven multi-country plans from the supplier listed as 3, including the 365-day plans at $55.99 and $93.99, begin their clock when you install the eSIM. Install those on arrival, not at home. The difference is explained in When Does a Travel eSIM’s Validity Clock Actually Start?
We compared stacking against long plans across many destinations in our 30, 60 and 90 day long-stay guide. Australia is one of the clearer cases for stacking because its single-country plans are cheap and none of them run long.
Are there unlimited eSIM plans for Australia?
Seven Australia-only plans are sold as unlimited, and every one of them has a limit written into the listing.
| Plan | Validity | Price | Per day | What “unlimited” means in the listing |
|---|---|---|---|---|
| Airalo Unlimited | 3 days | $12.99 | $4.33 | 3 GB a day at full speed, then up to 1 Mbps until the daily reset |
| Airalo Unlimited | 5 days | $15.99 | $3.20 | Same daily rule |
| Airalo Unlimited | 7 days | $20.99 | $3.00 | Same daily rule |
| Airalo Unlimited | 10 days | $26.99 | $2.70 | Same daily rule |
| eSIMGo Premium Unlimited | 5 days | $25.99 | $5.20 | 30 GB at full speed in total, then 2 Mbps |
| eSIMGo Premium Unlimited | 10 days | $38.99 | $3.90 | 60 GB at full speed in total, then 2 Mbps |
| eSIMGo Premium Unlimited | 15 days | $51.99 | $3.47 | 90 GB at full speed in total, then 2 Mbps |
None of them lasts longer than 15 days, and the cheapest per day is $2.70. Compared with $0.33 a day for the 10 GB 30-day plan, unlimited only pays off on a short, heavy trip, such as a week of working from a campervan with a laptop on hotspot. How these caps work in practice is covered in Unlimited Travel eSIMs: Fair Use, Throttling and Hotspot.
Will your eSIM work in the Outback?
In towns and along the main highways, usually yes. Away from them, often not, and no data plan changes that. Australia’s land area is about 7.7 million square kilometres. Telstra, which runs the largest network, says it covers 3 million square kilometres and 99.7% of the population when you count areas reached with an external antenna, and about 1.9 million square kilometres without one, according to reporting by the ABC in March 2026. A handheld phone therefore has no mobile signal across most of the continent.
Our product listings do not say which Australian network each plan connects to, so we cannot tell you whether a given plan uses Telstra, Optus or Vodafone. What we can say from the listings:
- 17 of the 21 Australia-only plans support 5G where available. The four Airalo unlimited plans are 4G only.
- Every one of the 63 plans covering Australia allows hotspot sharing, so one phone can keep a car full of devices online.
- None of the 63 includes calls or text messages. They are data only.
For remote driving, three things matter more than which eSIM you pick. Download offline maps for the whole route before you leave town. Know that any mobile phone in Australia can call Triple Zero (000) or 112 on any network that has coverage, even with no SIM or no credit, according to the Australian Mobile Telecommunications Association. And if you carry an iPhone 14 or later, Apple’s Emergency SOS via satellite works in Australia, so you can text 000 when there is no signal at all. Apple notes that satellite features are not offered on iPhones bought in mainland China and a few other countries, and older phones do not have it.
Before you land: visa, phone and install timing
Most short-term visitors need a visa arranged before they fly, and for passport holders who qualify, that is the Electronic Travel Authority (ETA). According to the Department of Home Affairs, the ETA costs a service charge of AUD 20 through the Australian ETA app, lets you visit as often as you like within 12 months, and allows stays of up to three months each time. For a longer stay you need a different visa.
Check your phone as well. Telstra and Optus switched off their 3G networks on 28 October 2024, and TPG Telecom/Vodafone had already closed its 3G network. From the same date, Australian rules required telcos to stop supplying services to phones that cannot call Triple Zero over 4G or 5G, as the Telecommunications Industry Ombudsman explains. A recent phone that supports 4G calling is the safe choice for a long trip.
Then the eSIM itself:
- Activation. 16 of the 21 Australia-only plans start on first data use. The other five, from TSimTech, are listed as starting on connecting to a network, and their plan notes also say validity starts on first data use. Either way, an Australia-only eSIM cannot connect before you arrive, so installing it at home a few days early costs you nothing.
- Exit country. Nine of the 21 Australia-only plans route traffic out through Singapore, three through the United Kingdom or Ireland, and nine do not say. Banking and streaming apps sometimes react to that. Details are in Which Country’s IP Will Your Travel eSIM Show?
- Phone number. With no calls or SMS included, keep your home SIM active for bank codes. We cover the options in Is a Data-Only eSIM Enough? If you are staying a year on a working holiday, you will likely want a local number anyway, and a travel eSIM covers the first weeks while you sort that out.
FAQ
What is the cheapest eSIM for Australia?
On 22 September 2026 the cheapest plan covering Australia was $4.49 for 1 GB over 14 days, an Australia and New Zealand pack. The cheapest Australia-only plan was $4.99 for 1 GB over 7 days. For 10 GB over 30 days, the cheapest was an Australia-only plan at $9.99.
Is there an Australia eSIM that lasts longer than 30 days?
Not as an Australia-only plan in our catalog. Every one of the 21 Australia-only plans lasts 30 days or less. Plans that cover Australia for 60, 90, 180 or 365 days exist, but all of them bundle other countries and cost more per gigabyte than buying a $9.99 10 GB plan each month.
Does an Australia eSIM work in New Zealand?
The Australia-only plans do not. All 42 multi-country plans covering Australia also cover New Zealand, including nine two-country packs. At 10 GB over 30 days, the cheapest combined pack cost $18.99, against $9.99 for Australia alone.
Can I call 000 with a data-only eSIM?
Yes. Emergency calls to 000 or 112 go through on any network with coverage, even without a SIM or credit, as long as your phone can call over 4G or 5G. Where there is no coverage at all, an iPhone 14 or later can text 000 through Emergency SOS via satellite.
Do Australia eSIMs include a phone number?
None of the 63 plans covering Australia in our catalog includes calls or SMS. They are data only, so you can use WhatsApp, FaceTime or other internet calling, and keep your home SIM on for text message codes.
Conclusion: monthly plans beat long plans for most stays
For a trip of up to a month, an Australia-only plan is almost always the cheapest option, with 10 GB for 30 days at $9.99 on the day we checked. For a longer stay, buying that plan again each month cost $29.97 for 90 days, well under any single long plan. The long multi-country plans are worth it only for light users who would rather install once, or for trips that also take in New Zealand and other countries. And whatever you buy, plan for the parts of the Outback where no network reaches.
Before you buy, confirm
- The plan’s validity covers your trip, or you have a plan for buying the next one within the two-month activation window;
- Whether you need top-ups, since the cheapest Australia-only plans cannot be topped up;
- When the clock starts, especially on yearly plans that start on installation;
- New Zealand is covered if your route goes there;
- Your phone can call over 4G or 5G, since Australia’s 3G networks are gone;
- Offline maps are downloaded for any stretch outside towns.
