How much eSIM data for a trip in Australia?
For 14 days in Australia with normal daily use, TripUtils estimates 6–9 GB. A 10 GB plan is the usual buffer. Not a live price. Maps, messaging and transit apps fit the normal band. Distances are large; that does not by itself mean the heavy setting — streaming video on mobile does. Type I at 230 V needs an adapter from Europe.

Roaming in Australia on an Austrian plan: what A1 and Drei charge
Australia is outside EU roam-like-at-home, so the EU data in an Austrian plan does not apply there. Published prices, checked on 22 Oct 2026 (euros incl. VAT):
| Network | Option | Data | Price |
|---|---|---|---|
| A1 | Roaming Pass (Zone 1) | per started GB | €4.90 |
| Drei | Roaming-Paket Go | 1 GB, 15 days | €5.00 |
| Drei | Roaming-Paket Go Select | 5 GB, 15 days | €10.00 |
For the 10 GB planning size (14 days), A1’s Roaming Pass would bill 10 × €4.90 = €49.00; on Drei, 2 packages (Go Select + Go Select) cover it for €20.00. A1 says the Roaming Pass is switched on automatically for every tariff signed since 24 June 2026, and it blocks roaming data at a default limit of €60, which you can raise yourself.
Magenta prices depend on the tariff — look them up in Magenta’s roaming finder. Older tariffs without these options can cost more. Sources: A1, Drei, Magenta.
Planning size
| Habits | 14-day range | Planning size |
|---|---|---|
| Normal (maps, messages, social) | 6–9 GB | 10 GB |
| Normal + daily video | 14–21 GB | 30 GB |
Assumptions and sources
Light 0.20 / normal 0.50 / heavy 0.95 GB per day, plus optional extras, plus about 20% buffer. No live retail prices.
December–January and school holidays lift stays on the east coast; GB still tracks phone use, not flight length.
These are planning ranges, not live prices.
Regional plans and guides
Australia is also covered by these Saily regional plans: Asia and Oceania (22 countries), Global (121 countries).

City pass for Sydney. Worth it only if you visit several paid sights – add up the single tickets first.

Common questions
Is 10 GB enough for 14 days in Australia?
Maps, messaging and transit apps fit the normal band. Distances are large; that does not by itself mean the heavy setting — streaming video on mobile does. Type I at 230 V needs an adapter from Europe. The 6–9 GB estimate plus buffer lands on 10 GB. Hotel Wi‑Fi is not counted. Streaming video on mobile is the usual reason to go larger.
Should I roam in Australia instead?
Australia is outside EU roaming. As of 22 Oct 2026, A1’s Roaming Pass bills €4.90 per started GB there (zone 1) and Drei sells 1 GB for €5 or 5 GB for €10, valid 15 days. Compare that with an eSIM quote for the same GB.
