Best eSIM for Australia & New Zealand 2026: Plans Compared
Compare eSIM plans for Australia and New Zealand. Network coverage, pricing, outback tips, and 5G availability in Sydney, Melbourne, and Auckland.
Quick answer
For Australia, choose an eSIM that connects to Telstra — it has the best rural and outback coverage by a wide margin. For New Zealand, Spark offers the most complete nationwide coverage. A 5 GB / 30-day Australia eSIM costs $6–12 USD; New Zealand is similar at $6–13 USD. If you’re visiting both countries, look for a combined Australia + New Zealand plan to save money and avoid managing two separate eSIMs.

Which networks do eSIMs use in Australia?
Australia has three mobile networks:
| Network | 4G population coverage | 5G cities (2026) | Geographic coverage | Best for |
|---|---|---|---|---|
| Telstra | 99.5% | Sydney, Melbourne, Brisbane, Perth, Adelaide, Canberra, Gold Coast | Largest — covers highways, regional towns, and some outback | Road trips, rural areas |
| Optus | 98.5% | Sydney, Melbourne, Brisbane, Perth, Adelaide | Second largest — strong in cities, weaker in remote areas | City-focused trips |
| Vodafone AU | 96% | Sydney, Melbourne, Brisbane | Smallest footprint — mostly metro areas | Budget city plans |
For travelers, Telstra is the clear winner if you’re leaving the cities. The difference between Telstra and the other two networks becomes dramatic once you leave the coast. On the Stuart Highway through the outback, Telstra has coverage for most of the route; Optus and Vodafone have long dead zones.
Most premium travel eSIM plans connect to Telstra or Optus. Budget plans often use Vodafone AU.
Which networks do eSIMs use in New Zealand?
New Zealand has three networks:
| Network | 4G population coverage | 5G cities (2026) | Best for |
|---|---|---|---|
| Spark NZ | 98% | Auckland, Wellington, Christchurch, Queenstown | Best overall coverage, including rural |
| One NZ (formerly Vodafone NZ) | 97% | Auckland, Wellington, Christchurch | Strong in cities and towns |
| 2degrees | 96% | Auckland, Wellington | Budget option, urban focused |
Spark has the best rural coverage in New Zealand, including parts of the South Island’s west coast and Fiordland approaches. For a South Island road trip, an eSIM on Spark’s network is the safest bet.
How much does an eSIM cost for Australia?
| Data | Duration | Typical price range |
|---|---|---|
| 1 GB | 7 days | $3–6 |
| 3 GB | 15 days | $5–9 |
| 5 GB | 30 days | $6–12 |
| 10 GB | 30 days | $10–20 |
| 20 GB | 30 days | $18–32 |
| Unlimited | 7 days | $12–22 |
Australia is moderately priced for eSIMs. Plans on Telstra’s network tend to cost 10–20% more than Vodafone AU plans, but the coverage difference justifies it for most travelers.

Is there a combined Australia + New Zealand eSIM?
Yes. Several providers offer regional plans that cover both countries on a single eSIM. This is ideal if you’re visiting both and don’t want to manage separate plans.
Combined plans are typically priced 10–30% more than a single-country plan of the same data size, but less than buying two separate plans. Check availability on our destinations page.
How is 5G coverage in Australian cities?
5G is well-established in Australia’s major cities as of 2026:
| City | 5G availability | Typical 5G speeds |
|---|---|---|
| Sydney | Widespread (CBD, suburbs, airport) | 150–500 Mbps |
| Melbourne | Widespread (CBD, inner suburbs) | 150–500 Mbps |
| Brisbane | Good (CBD, South Bank, airport) | 100–400 Mbps |
| Perth | Good (CBD, major suburbs) | 100–400 Mbps |
| Adelaide | Moderate (CBD, North Adelaide) | 100–300 Mbps |
| Gold Coast | Good (Surfers Paradise, Broadbeach) | 100–400 Mbps |
| Canberra | Moderate (CBD, parliamentary triangle) | 100–300 Mbps |
Not all travel eSIM plans include 5G access. If 5G speed matters to you, check the plan details. Standard 4G speeds in Australian cities (30–80 Mbps) are more than adequate for typical travel use.
How is coverage in the Australian outback?
The outback is where network choice matters most. Here’s a realistic breakdown:
| Route / Area | Telstra | Optus | Vodafone AU |
|---|---|---|---|
| Sydney to Melbourne (coastal) | Full coverage | Full coverage | Full coverage |
| Great Ocean Road | Good | Good | Patchy |
| Sydney to Brisbane (Pacific Hwy) | Full coverage | Full coverage | Mostly covered |
| Uluru / Ayers Rock | Covered | Limited | No coverage |
| Alice Springs | Covered | Covered | Limited |
| Stuart Highway (Adelaide to Darwin) | Mostly covered | Major gaps | Major gaps |
| Nullarbor Plain (Adelaide to Perth) | Patchy with gaps | Very limited | No coverage |
| Kakadu National Park | Jabiru township only | Jabiru township only | No coverage |
| Great Barrier Reef islands | Varies by island | Limited | Very limited |
| Tasmania — Hobart to Launceston | Full coverage | Full coverage | Good |
| Tasmania — west coast | Patchy | Very limited | No coverage |
Key takeaway: If your trip includes anything beyond the eastern seaboard cities, get an eSIM on Telstra’s network. The price difference is small; the coverage difference is enormous.
How is coverage on New Zealand’s South Island?
The South Island is stunning but remote. Here’s what to expect:
| Area | Spark | One NZ | Notes |
|---|---|---|---|
| Christchurch | Excellent | Excellent | Full 4G/5G |
| Queenstown | Excellent | Good | 5G available on Spark |
| Milford Sound road | Patchy | Patchy | No signal for last 30 km |
| West Coast (Hokitika, Greymouth) | Good in towns | Good in towns | Gaps between towns |
| Wanaka | Good | Good | |
| Te Anau | Good | Good | Gateway to Fiordland |
| Fiordland hiking tracks | No coverage | No coverage | Bring a PLB for safety |
| Aoraki / Mt Cook | Limited | Limited | Signal at village, not on tracks |
| Kaikoura | Good | Good | |
| Abel Tasman coast | Patchy | Limited | Download offline maps |
For multi-day hikes (Milford Track, Routeburn, Kepler), don’t rely on cell coverage. Carry a personal locator beacon (PLB) or satellite communicator.
How much data do I need for Australia or New Zealand?
| Usage pattern | Daily data | 7-day trip | 14-day trip | 21-day trip |
|---|---|---|---|---|
| Light (maps, messaging) | 300–500 MB | 3 GB | 5 GB | 7 GB |
| Moderate (social media, photos) | 500 MB–1 GB | 5 GB | 10 GB | 15 GB |
| Heavy (video calls, streaming) | 1–3 GB | 10 GB | 20 GB | 30 GB+ |
Australia and New Zealand trips tend to be longer and involve more driving than city-break destinations. Budget for slightly more data than you think you need — navigation and map loading adds up over long road trips.
Tips for road trips in Australia and New Zealand
- Download offline maps before you leave the city. Google Maps and maps.me both support offline areas. This is non-negotiable for outback driving.
- Choose Telstra (AU) or Spark (NZ) for the best highway coverage.
- Carry a car charger — navigation drains battery fast, and distances are long.
- Check coverage maps for your specific route before choosing a plan. Telstra and Spark both publish detailed coverage maps on their websites.
- Download entertainment (podcasts, music, Netflix) in advance. Long stretches of highway have no signal regardless of network.
- Consider a satellite communicator (Garmin inReach, ZOLEO) for remote outback or South Island wilderness driving. Cell coverage is not a safety net in truly remote areas.
