Australia and New Zealand in one trip: two countries, two plans and the Tasman in between
Two big countries, a three-hour flight between them and a lot of empty road. A connection plan built around long drives, national parks and two separate networks.
For a trip combining Australia and New Zealand, the usual set-up is two country plans: install both at home, use the Australia line first and switch to the New Zealand line after you land in Auckland or Christchurch. Cities are well served; outback roads, rainforest and much of the South Island have gaps, so drive with offline maps.
Why is this usually a two-plan trip?
Because the two countries are separate, far apart and rarely bundled together. Australia and New Zealand are about three hours apart by air across the Tasman Sea, with their own networks, and regional plans for Asia generally leave both out. When we checked TripoSIM's published lists on 7 November 2026, its Asia regional plan named neither; its Global plan named both. For most travellers, an Australia plan and a New Zealand plan are the direct fit, each with validity matched to its own part of the trip.

How should you split the trip?
Most itineraries spend the first two or three weeks in Australia and the last one or two in New Zealand, or the reverse. The country plans let each validity clock start when you first connect in that country, so the New Zealand plan does not run down while you are still in Australia, as long as its line stays switched off until you land.
| Part of the trip | Typical movement | What to plan for |
|---|---|---|
| Sydney and Melbourne | City days, a flight or the coast road | Well served; set up transport apps here |
| Great Ocean Road or Blue Mountains | Drives and walks | Gaps in valleys and on remote coast |
| Cairns and the reef | Boat days, rainforest | Little or no signal at sea and in dense forest |
| Auckland and the North Island | Drives to Rotorua and beyond | Towns served; hill country quieter |
| Queenstown and the South Island | Mountain roads, fiords | Long stretches with gaps; offline maps essential |
How do you plan long drives with gaps?
Both countries have long roads where coverage follows towns. The outback and the Australian far north are the obvious examples, but even popular routes can have quiet stretches: parts of the Great Ocean Road, the road to Milford Sound, the West Coast of the South Island. Plan each driving day the same way.
- Offline maps for the whole region, saved before you leave the city.
- The day's route loaded before you start the engine, so guidance continues through gaps.
- Fuel, food and the next bed known in advance, because the next town can be a long way off.
- Road conditions checked in the morning, especially on mountain roads in winter and in the tropical north during the wet season.
Which emergency numbers should you know?
Australia's emergency number is 000; New Zealand's is 111. Both countries also route 112 from mobile phones to emergency services. Emergency calls can often be made on any available network, but that depends on there being a network at all, which is not guaranteed in remote areas. For long remote trips, consider a dedicated satellite messenger or personal locator beacon; national park services in both countries recommend them for backcountry walks.
What do you do on the Tasman flight day?
Treat it as a border day. The evening before, save your New Zealand arrival details, rental car or transfer booking and first night's address offline. On landing, switch off the Australia line, switch on the New Zealand line, set it for data and allow data roaming on it. Keep the Australia eSIM installed until its plan has ended, in case you need a receipt or support.

Does a campervan trip change the plan?
Campervans are a popular way to see both countries, especially New Zealand's South Island. They change two things. First, you will spend more time between towns, so offline maps and a downloaded list of campsites matter more. Second, power: navigation all day drains a phone, so use the vehicle's charger and keep a power bank for walks. Many holiday parks have Wi-Fi in the main building, which is useful for evening downloads but rarely reaches every pitch. If you plan to work from the road, check that your plan allows hotspot use and expect to plan work around towns.
Which mistakes are common on this trip?
| Mistake | What happens | What to do instead |
|---|---|---|
| One plan bought for "Oceania" without checking the list | One of the two countries is missing | Find both countries by name, or use two country plans |
| New Zealand line switched on in Australia | Its validity may start early | Keep it off until you land |
| Driving remote roads on live maps only | Guidance stops in a gap | Offline maps and the route loaded each morning |
| Assuming 000 works in New Zealand | Confusion in an emergency | Note 111 for New Zealand, 000 for Australia |
A checklist before you fly
- Australia and New Zealand plans installed and labelled, or one plan whose list names both; both lines off.
- Offline maps for every road trip, downloaded on home Wi-Fi.
- Campervan or hire-car booking saved offline, with the depot's phone number written down.
- Emergency numbers noted: 000 in Australia, 111 in New Zealand.
Questions travellers ask
Is there one eSIM for Australia and New Zealand?
Some wider plans list both; regional Asia plans usually do not. Two country plans are the simple fit for most trips.
Will I have signal in the outback?
Expect long stretches without coverage away from towns. Drive with offline maps and plan fuel and stops in advance.
What are the emergency numbers?
000 in Australia and 111 in New Zealand. Both also route 112 from mobile phones.
When does the New Zealand plan start?
TripoSIM says its plans start when the eSIM first connects at the destination, so keep the New Zealand line off until you land.
