Australia eSIM with fast 5G coverage

Heading overseas from New Zealand? HelloRoam gives you data without the drama of swapping SIM cards at the airport. Getting connected on arrival is easy with a HelloRoam eSIM. You buy your plan before you leave home, scan the QR code, and land in Sydney, Melbourne, or Brisbane with data already active. HelloRoam's Australia plans connect to Telstra, Australia's largest network operator. Telstra runs 5G in all major cities and 4G LTE across coastal towns, regional centers, and the main highway corridors. Outback areas far from roads and the deep interior have no mobile signal, as distances are simply too large to cover economically. For the destinations most travellers visit, including the cities, coastal national parks, the Great Barrier Reef, and Uluru, coverage is reliable. A HelloRoam eSIM saves you the cost and time of buying a local SIM at the airport and gives you a fixed prepaid rate for your whole trip.

Australia — mobile connectivity coverage

Mobile connectivity guide for Australia

Australia is the most popular destination for New Zealanders and the mobile coverage across the major coastal cities is choice. Optus covers Sydney, Melbourne, Brisbane, Perth, Adelaide, and the Gold Coast with excellent 5G and 4G.

The Australian Outback has very limited coverage across all networks, but the coastal tourist trail is very well served. A HelloRoam eSIM means you step off your trans-Tasman flight already connected without hunting for a phone shop at the airport.

HelloRoam connects to Optus 5G in Australia
5G and 4G on Optus across Sydney, Melbourne, Brisbane, Perth, and the Gold Coast
Connect the moment you land at Sydney, Melbourne, or Brisbane airports
Great for OE adventures, work trips, and family visits across the Tasman

eSIM Travel Tips for Australia

Trans-Tasman trips: set up your eSIM at home first
Install your HelloRoam eSIM at home before your Air NZ or Jetstar flight to Australia. Enable mobile data when you land in Sydney or Melbourne and you are straight on Australian coverage. No need to find an Optus or Telstra store on arrival. Very sweet.
Australian Outback and remote areas have no signal
If your OE or adventure itinerary takes you into the Outback, along the Nullarbor, or deep into national parks, download offline maps before you go bush. All Australian carriers have limited coverage away from the coast.
Australian transport apps need live data
Sydney's Opal card app, Melbourne's Myki, Brisbane's go card, and Perth's Transperth all have real-time journey planning. Your HelloRoam eSIM keeps these running from the moment you clear immigration at Sydney or Melbourne Airport.
Keep your NZ number active for calls home
Run your NZ SIM for calls and your HelloRoam eSIM for data. Family and mates can still ring your usual NZ number while you are exploring Melbourne's laneways or Sydney Harbour. Dead easy on a dual SIM phone.
The Gold Coast and Byron Bay are well covered
Popular NZ visitor destinations like the Gold Coast, Byron Bay, and the Whitsundays all have good 4G coverage. Boat trips to the Great Barrier Reef will drop signal on the water but resort areas and dive shop zones are covered.

Mobile networks in Australia: what NZ visitors need to know

HelloRoam connects on Optus in Australia. Optus is the second-largest carrier in Australia with excellent 5G and 4G coverage in all major cities and along the coastal tourist routes. Optus has a roaming partnership with Telstra that improves rural coverage in some areas. Your eSIM connects automatically to the best available Optus signal.

Optus: 5G

Best time to visit Australia from New Zealand

Australia is a year-round destination for NZ travellers. Queensland and the Gold Coast are popular in winter (June to August) when Australia is warm and NZ is cold. Sydney and Melbourne are brilliant in late spring and autumn. The major NZ holiday periods of Christmas, Easter, and school holidays see the most NZ visitors heading over. Book flights early during the August school holiday rush.
