Australia's vastness creates a stark divide between carriers. In Sydney, Melbourne, and Brisbane, all three major carriers (Telstra, Optus, Vodafone) offer similar 5G speeds. But the moment you leave the city, the gap becomes dramatic. Optus covers 99.4% of the Australian population and has the only meaningful signal along remote highways like the Stuart Highway (Adelaide to Darwin) and the Nullarbor Plain. Ovosim leverages Optus infrastructure to give you coverage in both urban and rural environments.
The Great Ocean Road between Melbourne and the Twelve Apostles is one of the world's iconic road trips. Optus maintain 4G coverage through most of the coastal towns (Lorne, Apollo Bay, Port Campbell). The limestone stack viewing areas have good signal. Download offline maps as backup for the inland detour sections near Otway National Park where signal can drop briefly.
Cairns, Port Douglas, and the Whitsundays are well-covered by Optus on land. However, once you are on a dive boat or pontoon on the outer reef, you are beyond cellular range. This is expected — use the boat's radio for emergencies, and enjoy being offline for the day. Your eSIM will reconnect the moment you return to the marina.
Since 2020, Australian law requires all prepaid SIM cards to be registered with a valid ID before activation. This adds 10–20 minutes at the airport kiosk and requires your passport. Ovosim operates under international roaming agreements and requires zero registration — no passport, no form, no waiting.
In the Australian Outback, always carry a satellite communicator (Garmin inReach, SPOT) as a backup. Mobile coverage on even the best networks disappears completely in remote areas. For city travel and the standard tourist route, Ovosim's Optus access is more than sufficient.

Yes. Cairns, Port Douglas, Airlie Beach, and the Whitsunday mainland are covered. Signal disappears once you are on the open water of the Great Barrier Reef, which is expected.
