12 Best eSIM for Australia 2026: Telstra vs Everyone

On this page

The catch: on 30 June 2026 Telstra lost 860,000 square kilometres off its coverage map overnight. It still covers nearly twice the ground of anyone else.

The podium

Sim Local. Names Telstra and Optus on the actual product page, not in marketing copy, and 10GB lands at $13.05 after code. That dual arrangement is what you want on a driving trip.

BNESIM. Twenty gigabytes for $10.51 and fifty for $23.36. Nothing else is close, and the non-expiring packs mean leftover data waits for your next trip instead of dying.

Maya. The only unlimited plan that falls to 10 Mbps rather than 1 Mbps when you cross the daily line. Ten megabits still holds a video call. One does not.

The thing every Australia eSIM guide is about to get wrong

On 30 June 2026 every Australian carrier had to republish its coverage map under a new mandatory national standard, and the numbers moved hard. Telstra’s mapped footprint fell from 3 million square kilometres to 2.14 million, a loss of 860,000 square kilometres in a single day.

Nothing changed on the ground. The standard simply forbids showing anything weaker than minus 115 dBm as covered, so the map finally matches the signal.

Telstra also stopped publishing a population coverage figure at all, having last claimed 99.7 percent.

Here’s the thing. Even after losing nearly a third of its map, Telstra still covers 2.14 million square kilometres against roughly 1.2 million each for Optus and Vodafone AU. That is 27.8 percent of the Australian landmass against 15.6 percent.

Telstra disputes the framing and has a point worth hearing: 1.5 million customers a month still use the network in areas now shown as blank, and roughly 57,000 emergency calls a year come from them. Marginal coverage is not no coverage.

Now the part that matters for your wallet. Of the 16 providers I priced, only Sim Local, Holafly, Roamless and Amigo eSIM publish Telstra as an Australian partner.

Airalo, Ubigi, aloSIM, Global YO, BNESIM and Maya all name Optus. Nomad, Saily, GigSky, MobiMatter, Jetpac and Instabridge name nobody.

That is not a scandal. Optus is genuinely the faster network and reaches 99.11 percent of the population. It just means the one specification that decides your outback trip is the one most brands leave blank, and my stock position applies: if they will not name the carrier, assume it is the cheapest one available to them.

Which network is best in Australia, Telstra or Optus?

Optus is faster, Telstra reaches further, and which one you want depends entirely on whether your trip leaves the coast.

Australia runs three radio networks: Telstra, Optus, and Vodafone AU under TPG Telecom.

The May 2026 Opensignal Australia report, measured across the first quarter, splits the awards cleanly.

Metric	Telstra	Optus	Vodafone AU
Download speed	51.7 Mbps	58.3 Mbps	39.3 Mbps
Upload speed	6.9 Mbps	7.1 Mbps	8.8 Mbps
5G download	171.7 Mbps	199.9 Mbps	161.8 Mbps
Coverage Experience	9.6 / 10	not awarded	not awarded
5G Coverage Experience	8.0 / 10	not awarded	not awarded
Availability	not awarded	99.4%	99.4%
Mapped area	2.14m km²	~1.2m km²	~1.2m km²

Optus took the speed crown for the tenth report running. Telstra took Coverage Experience at 9.6 out of 10, and runs at least 2,000 more mobile sites than anyone else.

You can also check Telstra’s official coverage map before heading into regional areas.

One structural change worth knowing: since January 2025, Vodafone AU rides Optus radio across regional Australia under an 11 year network sharing deal the ACCC cleared in September 2024.

TPG gained access to 2,444 Optus regional sites, taking its 4G footprint from 400,000 square kilometres to roughly 1.2 million.

So in the bush, “Vodafone” and “Optus” are increasingly the same antennas. There are really two regional networks in Australia, not three.

Australia eSIM speed test results

Real-world eSIM speeds in Australia depend on location, network congestion, device, and signal strength. The results below show typical performance across major cities and regional travel routes.

Location	Network Tested	Download Speed	Upload Speed	Ping	Best For
Sydney CBD / Surry Hills	Telstra + Optus 5G	170–260 Mbps	13–17 Mbps	20–35 ms	Streaming, maps, hotspot use
Sydney Airport Area	Telstra + Optus 5G	150–250 Mbps	12–18 Mbps	20–40 ms	Landing day connectivity
Melbourne CBD / Fitzroy	Telstra + Optus 5G	170–275 Mbps	13–16 Mbps	20–35 ms	Remote work and daily use
Great Ocean Road / Lorne	Telstra 4G/5G	50–150 Mbps	8–15 Mbps	30–50 ms	Road trips and regional travel

Regional Australia Coverage Notes

Location	Recommended Network	Why It Matters
Brisbane	Telstra or Optus	Strong urban performance
Cairns	Telstra preferred	Better regional coverage
Port Douglas	Telstra preferred	More reliable outside city areas
Atherton Tablelands	Telstra preferred	Better rural connectivity

The best Australia eSIMs, ranked

1. Sim Local, best eSIM for Australia overall

Sim Local wins because it names Telstra and Optus on the individual product page rather than in vague marketing copy, and 10GB costs $13.05 after our code.

Two networks means Optus for speed in the cities and Telstra when the towers thin out past the last roadhouse.

The unlimited tiers are the other reason. Sim Local puts the daily allowance in the product name instead of burying it in terms, and Unlimited Pro allows 10GB a day at full speed. That is the highest published daily figure of any provider selling Australia, and five times what Nomad allows.

Plan	Data	Validity	List	After ESIMDUDE10	Per GB
Australia 3GB	3GB	7 days	$7.75	$6.98	$2.33
Australia 5GB	5GB	30 days	$9.75	$8.78	$1.76
Australia 10GB	10GB	30 days	$14.50	$13.05	$1.31
Australia 20GB	20GB	30 days	$25.25	$22.73	$1.14
Unlimited, 5GB per day	Unlimited	7 days	$18.75	$16.88	n/a
Unlimited Pro, 10GB per day	Unlimited	7 days	$23.50	$21.15	n/a
Unlimited Pro, 10GB per day	Unlimited	15 days	$52.25	$47.03	n/a

What works. Tethering is allowed. Validity starts when the profile attaches to an Australian network, not when you install it, so you can set it up at home safely.

The SEA and Oceania regional plan covers Australia and New Zealand together from $4.75 for 1GB over three days, up to $26.25 for 10GB over 30 days, which is the buy if you are doing both countries.

What doesn’t. No phone number, no SMS, so bank codes will not arrive here. And it is not the cheapest option, which matters if your route never leaves Sydney.

Verdict: 4.7 / 5. Speed 4.5, price 4.4, support 4.6, features 4.9, app 4.6.

More in our eSIM reviews hub.

2. Roamless, the one that never throttles

Roamless is the second provider that names both Telstra and Optus on its own Australia page, and it sells credit rather than packages. 

FLEX data runs $2.45 a gigabyte and never expires, so whatever you do not use is waiting for the next trip.

The spec sheet carries a line I have not seen anywhere else in this category: speed limit, never.

Roamless publishes no fair use throttle and sells no unlimited plan, so there is no daily cliff to fall off. A free 500MB trial confirms the profile attaches before you spend anything.

Plan	Data	Validity	Price	Per GB
Trial	500MB	one off	Free	n/a
FLEX credit	1GB	never expires	$2.45	$2.45
Package	10GB	30 days	$17.95	$1.80
Package	20GB	30 days	$29.95	$1.50
Package	50GB	30 days	$44.95	$0.90

What works. Unlimited hotspot, auto connection on arrival, and credit that outlives the trip.

If you visit Australia every couple of years this beats buying a fresh package and binning the remainder.

What doesn’t. No eSIMTweaks code exists, so list price is what you pay, and at $1.80 a gigabyte for 10GB it is 37 percent dearer than Sim Local after our discount.

Voice sits in a separate Roamless Numbers product.

Verdict: 4.5 / 5. Speed 4.5, price 4.0, support 4.4, features 5.0, app 4.5.

3. Airalo, the widest ladder and the deepest discount

Airalo sells Australia under the local package name Yes! Go!, runs on Optus, and offers the best big data value of any mainstream brand at $40.50 for 50GB after code.

The ladder runs from 1GB over three days to 50GB over 30 without a gap, which is why I hand it to people who do not yet know how much data they need.

Plan	Data	Validity	List	After ESIMDUDE10	Per GB
Yes! Go!	1GB	3 days	$4.00	$3.60	$3.60
Yes! Go!	5GB	30 days	$11.00	$9.90	$1.98
Yes! Go!	10GB	30 days	$18.00	$16.20	$1.62
Yes! Go!	20GB	30 days	$30.00	$27.00	$1.35
Yes! Go!	50GB	30 days	$45.00	$40.50	$0.81
Yes! Go! Unlimited	3GB per day, then 1 Mbps	7 days	$26.50	$23.85	n/a
Yes! Go! Unlimited	3GB per day, then 1 Mbps	30 days	$66.50	$59.85	n/a

What works. If you have never bought from Airalo, ESIMADVICE15 takes that 50GB pack to $38.25, or 77 cents a gigabyte.

The Oceanlink regional plan covers eight countries including New Zealand from $4.50, with 20GB over 30 days at $49.00.

What doesn’t. Optus only, so no Telstra fallback. Australia is data only with no number and no SMS. And the unlimited tiers drop to 1 Mbps after 3GB a day, which is a hard landing.

Verdict: 4.4 / 5. Speed 4.6, price 4.5, support 4.5, features 4.0, app 4.8.

The contenders

4. BNESIM: the cheapest data in Australia, full stop

Twenty gigabytes over 30 days costs $10.51, which is 53 cents a gigabyte, and fifty gigabytes costs $23.36 at 47 cents.

Nothing else here is close, and that 47 cents matches what an Australian pays on a local Boost recharge.

Type	Data	Validity	Price	Per GB
Expiring	10GB	30 days	$7.00	$0.70
Expiring	20GB	30 days	$10.51	$0.53
Expiring	50GB	30 days	$23.36	$0.47
Expiring	100GB	30 days	$46.74	$0.47
Non expiring	20GB	never	$12.84	$0.64
Non expiring	50GB	never	$29.21	$0.58

The non expiring family is the clever bit.

For about a dollar more per ten gigabytes the data never dies, and one profile carries multiple countries so you add destinations rather than installing a new eSIM at each border.

So why is it not first?

Optus only, no eSIMTweaks code, and prices are natively in euros so the dollar figure drifts with the exchange rate.

On price alone this is the cheapest eSIM Australia sells, and it is not close. City trip, buy it and stop reading. Road trip, pay the extra for Telstra.

5. Maya: unlimited with a soft landing

Maya sells Australia as unlimited only, and it is the pick for anyone who does not want to count gigabytes, because of the throttle rather than the price.

Published guidance drops you to 10 Mbps after 3GB in a day, falling to 1 Mbps only if very heavy use continues.

Plan	Validity	List	After ESIMTWEAKS10	Per day
Australia Unlimited	3 days	$9.99	$8.99	$3.00
Australia Unlimited	7 days	$19.99	$17.99	$2.57
Australia Unlimited	14 days	$27.99	$25.19	$1.80
Australia Unlimited	30 days	$49.99	$44.99	$1.50

Ten megabits streams, holds a video call and uploads a day of photos. One megabit runs maps and messaging and nothing else. That gap is worth more on a two week trip than five dollars off the sticker, and it is why Maya beats every other unlimited plan here on the thing that actually bites.

Hotspot is included, the network is Optus, and you pick your activation date at checkout rather than having one forced on you.

6. Global YO: the volume play

One hundred gigabytes over 60 days costs $42.14, which is 42 cents a gigabyte and the lowest rate anywhere in this guide.

Fifty gigabytes over 45 days runs $29.34 and twenty gigabytes over 30 days runs $15.14.

Data	Validity	Price	Per GB
5GB	15 days	$7.44	$1.49
10GB	30 days	$10.24	$1.02
20GB	30 days	$15.14	$0.76
50GB	45 days	$29.34	$0.59
100GB	60 days	$42.14	$0.42

The long validity windows are what separate it from BNESIM. Forty five and sixty day terms suit working holidaymakers and slow travellers rather than the 30 day cycle everyone else sells.

Global YO names Optus openly, supports hotspot, requires no ID, and lets you hold the profile and activate manually when you land.

It also lists day plans from $8.99, but the daily allowance on those is stated two different ways across its own materials. Take the capped gigabyte plans where the number is unambiguous.

7. Holafly: unlimited with Telstra underneath

The third Telstra confirming provider, and the only one publishing no numeric daily cap at all. Unlimited runs $27.50 for 7 days and $73.90 for 30, which works out at $3.93 and $2.46 a day.

The fair use wording promises any speed reduction lasts no more than one day. That is either the most generous policy here or the least transparent, depending on your mood, and I lean towards the second.

Hotspot is capped at 1GB a day, which rules it out entirely if you work off a laptop.

Alternatives sit in our Holafly alternatives guide.

8. Saily: unlimited hotspot, undisclosed network

Saily allows 5GB a day before throttling and permits unlimited hotspot sharing, at $16.19 for 10GB over 30 days after code. Unlimited runs $31.49 for 10 days after discount.

The 30 day activation window is worth knowing: buy it more than a month before you fly and it starts itself.

Saily will not name its Australian carrier, describing it only as the best local networks, which in a country with this coverage spread is the one spec I want and cannot have.

Listed on the Saily coupon code page.

9. Nomad: sharp on big packs

Fifty gigabytes for $27.20 after ESIMDUDE15 is 54 cents a gigabyte, and 20GB lands at $20.40. That is the second best big data rate here after BNESIM, and the discount is the deepest of any code we hold.

The catches are the same everywhere Nomad operates: unlimited tiers cap at 2GB a day before dropping to 1 Mbps, which is the lowest daily allowance in this entire guide, and buying with a code makes the plan non refundable once activated.

The Australian carrier is not published. Current offers sit on the Nomad promo code page.

The rest

10. Ubigi

Optus, and the cheapest dedicated Australia and New Zealand pairing I found at $5.00 for 1GB over 7 days across both countries.

Australia only runs $14.00 for 10GB over a week. Worth it purely for the two country pack.

11. Amigo eSIM

Confirms Optus and Telstra MobileNet, which puts it in the four. Prices in pounds, so 18GB over 30 days is £26.00, or £22.88 after our 12 percent ESIMDUDE code.

Buy it if you are billing in sterling.

12. GigSky

The free 100MB seven day trial is genuinely useful for confirming your handset takes the profile.

At $25.49 for 10GB after ESIMADVICE15 it is the dearest per gigabyte here, so use the trial and buy elsewhere.

MobiMatter, Jetpac and Instabridge.

MobiMatter resells other brands at 20GB for $13.99 and pays ESIMDUDE cashback.

Jetpac allows unrestricted hotspot and holds unactivated packs three months.

Instabridge has the cheapest entry point at $2.00 for 1GB. None names a network.

If you are shopping as an eSIM Australia tourist rather than a resident, the two week row is the one that fits 45 percent of arrivals.

What to do before you fly and on landing?

Install the profile at home on stable wifi. The activation code in a QR is single use by design, which is why a failed download at the airport burns it. I learned that at Bangkok arrivals on hotel wifi that dropped halfway, and the profile was gone.

Leave data roaming switched off on the travel line until you land. Validity on almost every plan here starts when the profile attaches to an Australian network, not when you install it, so early setup costs you nothing.

Keep your home SIM in the phone with data off. Every plan in this guide is data only, so bank one time passcodes still need somewhere to arrive.

Check VoLTE support before you go. Australia shut down all 3G in 2024, Vodafone in December 2023, Telstra and Optus on 28 October 2024, and a handset without VoLTE on Australian bands cannot place a voice call at all.

Common Australia eSIM problems and fixes

Best eSIM for Australia FAQs

Buy the network, not the brand

Australia is a coverage country, not a speed country. Every provider here is fast enough in Sydney and Melbourne, and the thing that separates them is what happens on the road north of Cairns or west of Adelaide.

Twenty seven point eight million Australians live in a country almost the size of the continental United States, and 87 percent of them sit within 50 kilometres of the coast, on roughly a fifth of one percent of the landmass. Sydney to Cairns is 2,416 kilometres. Perth to Adelaide across the Nullarbor is 2,692.

So: leaving the coast, buy Sim Local at $13.05 for 10GB after ESIMDUDE10 and take the Telstra fallback. Staying on it, buy BNESIM at $10.51 for 20GB and spend the difference on coffee. Want unlimited, buy Maya at $17.99 for a week after ESIMTWEAKS10 and enjoy the 10 Mbps floor.

Install it before you fly. Every single time.

Good on ya, and mind the roos at dusk.
