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

Australia's Mobile Network in Detail
Australia has three main operators: Telstra, Optus, and Vodafone Australia. HelloRoam's Australia plan connects via Telstra, which operates the country's largest 5G and 4G LTE network by geographic coverage.
Telstra's 5G network is live in Sydney, Melbourne, Brisbane, Perth, Adelaide, and Canberra. In cities, average download speeds run 100 to 400 Mbps on 5G and 30 to 80 Mbps on 4G. Major regional towns including Cairns, Darwin, Townsville, Hobart, and Byron Bay have solid 4G coverage. The Bruce highway in Queensland, the Pacific highway in New South Wales, and the Hume highway between Sydney and Melbourne all have 4G along the carriageway.
Coastal national parks including the Blue Mountains, Daintree Rainforest, and the Whitsundays have variable coverage. Signal is typically present at park visitor centers and main trails but drops in dense forest and off-track areas. The Outback interior, including the Nullarbor Plain, the Great Victoria Desert, and the Kimberley region, has no signal for long stretches. Roadhouses on the Stuart highway and Outback highways often have limited signal in the immediate area. Uluru and Kata Tjuta have coverage at the main visitor area and resort precinct. Australian travellers should confirm their handset is unlocked and supports the local network bands.
