Internet and Wi-Fi in Australia
What to expect from mobile coverage, public Wi-Fi and data options in Australia — and the simplest way to get online as a visitor.
Mobile coverage in Australia
Strong 4G/5G in cities and along the east coast; expect long dead zones in the Outback and between towns.
Local networks
Our Australia eSIM connects to these local mobile networks, the same ones domestic SIM cards use:
- Optus
Can you rely on public Wi-Fi?
Hotels, cafes and airports in Australia usually offer Wi-Fi, but it rarely helps when you need a connection most: navigating between places, checking transport in real time, or calling a ride from the street. Public networks are also unencrypted more often than not. Treat Wi-Fi as a bonus, not a plan.
The easiest way to get online
A prepaid eSIM for Australia installs on your phone before you leave home and connects to a local network automatically when you land — no store visits, no paperwork, no roaming fees. Plans start at $0.51.
