The harbour, the coastal walk from Bondi to Coogee, and the Blue Mountains as a day out. Tap a contactless card on every ferry and train; Sunday fares are capped very low, which is when locals travel.

One package for Australia and New Zealand, so crossing the Tasman is not a second purchase. Install it at home and it keeps working when you land on the other side.

The allowance is shared across all included countries — it does not reset per country or at borders.
Continue to checkoutWhere it works
2 countries on one package. A few of them:
- Included countries
- One data allowance for the whole package — use it in any mix of the 2 included countries. It is not per country.
- When validity starts
- Your package starts when your phone first connects to a network at the destination — not when you install it. Crossing a border does not restart it.
- Entering another included country
- Your phone picks up a partner network in the new country automatically — keep data roaming on for the onesim line. No settings to change and nothing to reinstall.
- Outside the covered countries
- The package does not connect. Your phone falls back to Wi-Fi or your home SIM if you allow it — check the list before you go, and look at another onesim package for uncovered stops.
- Calls and texts
- onesim is data-only. Calls and messages work over data in apps like WhatsApp or FaceTime; your usual SIM keeps your number.
- Support and refunds
- Message the onesim support team from the app or the website. If a package cannot be installed or used, the refund policy explains what applies. Refund policy
Route idea · Sydney and the South Island
Two countries, three weeks.
The pairing that works best for a first trip: one Australian city, one Australian coast, and the South Island. The line below is an illustration, not a map.

2The Queensland coast · Days 6–10
Fly rather than drive: Noosa to Airlie Beach is eleven hours by road and there is nothing in between worth two days of it. The Whitsundays for the sand, Cairns or Port Douglas for the reef. May to October is the dry season and the time to come.
eSIM for Australia
3New Zealand's South Island · Days 11–21
Three hours across the Tasman. Christchurch, Aoraki, Queenstown, Fiordland and the west coast make a two-week loop on their own; ten days does it at a pace. Fly into one country and out of the other on an open-jaw ticket.
eSIM for New ZealandHow the plan fits this route
Both countries are on this package, so the Tasman crossing does not need a second eSIM or a second installation — the line is working when the plane doors open in Auckland or Christchurch. Worth knowing that it is these two countries rather than the wider Pacific: the island nations are not on the list.
Before you go
Three things that catch first-timers.
The paperwork is small and mandatory. Australia wants an ETA, applied for in its official app for AUD 20. New Zealand wants an NZeTA plus a NZ$100 International Visitor Levy, paid together before you fly. Neither takes long; both are refused at the gate if missing.
Biosecurity at both borders is the strictest you will meet, and it applies to the Tasman crossing as well as to arriving from home. Declare food, and expect hiking boots to be inspected and possibly cleaned. The fine for not declaring is not a formality.
Coverage follows population, which in Australia means the coast and in New Zealand means the towns. The outback, the fiords, the alpine passes and most of the west coast have nothing. Download each leg before you drive it.
Oceania plan questions.
Answers for trips across more than one country.
Open “See covered countries” and search each stop. The list is the authoritative source: if a country is on it, this package works there; if it is not, we point you to another onesim package if one covers it.
No. Validity runs from your first connection in any included country and continues for the plan’s full duration wherever you are on the list.
The package will not connect there. Check whether another onesim package covers that stop, or plan on Wi-Fi for it.
Yes. Your account has one onesim eSIM, and you refill it with any regional package from anywhere in the world — from the website or the app. The new package is added to the eSIM already on your phone; there is nothing to install again.
