HelloRoam eSIM (8.8/10, 31/31 activations) has the best pricing for Oceania: runs on Telstra infrastructure in Australia from $0.29/GB, best app UX, instant activation. Cheaper than the $30 AUD airport tourist SIM. New Zealand and Australia need separate plans or a multi-country eSIM.
Oceania spans from well-connected Australia and New Zealand to remote Pacific islands where a single carrier may operate under a government franchise. Australia has Telstra, Optus, and Vodafone competing for prepaid customers, with tourist SIMs available at airport kiosks for $20 to $30. New Zealand follows a similar pattern with Spark and One NZ. The Pacific Islands: Fiji, Vanuatu, Tonga, and Samoa mostly run Digicel or Vodafone franchises, with plans priced $8 to $15 and coverage limited to main towns and resort areas.

What is the best SIM card for tourists in Australia?
Telstra has the best coverage in Australia, including regional areas, the Nullarbor Plain, and along major highways. Their prepaid tourist SIM costs around $30 AUD for 28 days with 10 GB. Optus and Vodafone are cheaper in cities but have weaker coverage outside metro areas. Telstra is worth the premium if you plan to travel beyond major cities.
Where can I buy a SIM card in Australia?
All major Australian airports (Sydney, Melbourne, Brisbane, Perth) have Telstra, Optus, and Vodafone counters in arrivals. You can also buy SIMs at 7-Eleven stores, Woolworths supermarkets, JB Hi-Fi electronics stores, and carrier retail stores. Online pre-order with airport pickup is also available from Telstra and Optus.
Does a New Zealand SIM card work in Australia?
No. New Zealand and Australia have no free roaming agreement. Spark, One NZ (formerly Vodafone NZ), and 2degrees all charge roaming rates for use in Australia. Buy a separate Australian SIM or use an eSIM that covers both countries.
Is mobile internet available in the Pacific Islands?
Yes, with limitations. Fiji, Samoa, Tonga, and Vanuatu all have mobile internet from Digicel or Vodafone, but coverage is concentrated in main towns and resort areas. Remote islands and rural areas often have no signal. Papua New Guinea has Digicel coverage in Port Moresby and Lae but very limited rural connectivity.
What is the cheapest SIM card in Oceania?
Pacific Island nations offer the cheapest SIM cards in Oceania. Fiji, Samoa, Tonga, and Vanuatu have plans from $8 to $10 USD for a week of data. Australia and New Zealand are significantly more expensive, with typical tourist plans running $20 to $35 USD for a 30-day plan.
