Telstra runs 5G in all major cities and 4G LTE across coastal towns, regional centers, and the main motorway corridors.

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 the long journey from Dublin.
- HelloRoam connects to Optus 5G in Australia

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. Switch on data when you land in Sydney or Melbourne and you're online straight away, with no need to hunt for a phone shop.
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
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 main coastal tourist routes. Rural and Outback coverage is limited as in all of Australia. Your eSIM connects automatically to the best available Optus signal.

HelloRoam eSIM vs Irish carrier roaming in Australia

|---|---|---|---|
| Typical cost | From €3.02 total | €8.64–€25.93 total | — |
| Details | Plans from €3.02. Buy before your 22-hour journey, scan a QR code at home, and arrive in Sydney or Melbourne already on Australian 5G data. | Available at airports and Coles/Woolworths supermarkets. Buying a local plan is great for longer stays but an eSIM is more convenient for the first days after arrival. | Australian roaming from Irish carriers is expensive. Daily add-ons can add up quickly. A month in Australia on working holiday roaming costs far more than a HelloRoam plan from €3.02. |

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
