Good to Know
- Optus is the only carrier with a dedicated SIM booth at Cairns Airport, but Telstra offers superior regional coverage if you can wait to visit a Telstra store in town.
- NBN technology varies by address—check your specific location for FTTP, HFC, FTTC or FTTN availability before committing to a plan; most providers offer address-check tools.
- Mobile coverage deteriorates significantly outside Cairns city: inland roads, Daintree Rainforest, and drives to Cooktown have spotty or no signal even on Telstra; consider Telstra for these trips.
- e-SIM is convenient for quick activation before arrival, but local prepaid SIM cards often offer better value per GB if staying longer and have time to visit a carrier store.
- Prepaid plans typically include unlimited local calls and texts; data limits vary; going over data limit on prepaid SIM simply stops data access rather than incurring overage charges.
