Australia eSIM with fast 5G coverage

Flying abroad? HelloRoam gives Irish travellers a simple way to get mobile data without buying a local SIM 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 motorway 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 has excellent 5G and 4G coverage in its coastal cities. Optus covers Sydney, Melbourne, Brisbane, Perth, Adelaide, and the Gold Coast well. Outback areas and very remote National Parks have very limited or no coverage, but the tourist coastal trail is well served. Ireland has a massive connection to Australia through emigration, gap year travel, and working holiday visas. A HelloRoam eSIM means you arrive in Sydney or Melbourne already connected after a 22-hour journey from Dublin. 185+.

eSIM Travel Tips for Australia

Activate at home before your long-haul journey from Dublin
Getting to Australia from Ireland typically involves one or two connections and 22 to 26 hours of travel. Set up your HelloRoam eSIM at home before you even leave for Dublin Airport. Enable data when you land in Sydney or Melbourne and you are connected immediately without the hassle of finding a Optus or Telstra store.
The Outback and remote areas have no signal
Australia's vast interior has very limited mobile coverage. If you are driving the Stuart Highway, exploring Kakadu, or camping in remote national parks, download offline maps and let people know your itinerary. Coastal cities and the tourist trail are well covered.
Australian cities have excellent coverage
Sydney, Melbourne, Brisbane, and Perth all have strong 5G and 4G throughout their city centres and suburbs. Apps like Opal for Sydney transport, Myki for Melbourne, and go card for Brisbane all run perfectly on a HelloRoam connection.
Working holiday visas: data needs from day one
Many Irish people arrive in Australia on Working Holiday Visas and need data from the moment they land to find accommodation, jobs, and navigate their new city. A HelloRoam eSIM bridges the gap until you sort a local Australian SIM plan.
Call home to Ireland on WhatsApp
Use WhatsApp, FaceTime, or Google Meet for calls home to Ireland. Data costs are much lower than international calls. With your HelloRoam eSIM running and your Irish SIM still active in your dual SIM phone, family can still reach you on your Irish number.

Mobile networks in Australia: what Irish visitors need to know

Best time to visit Australia from Ireland

Australia's seasons are reversed from Ireland. December to February is Australian summer, which is ideal for beaches and outdoor activities in the south. June to August is Australian winter, which is mild in Sydney and Melbourne and perfect for the Outback and Queensland. Irish travellers often time visits for the Australian summer which coincides with Christmas in Ireland.
