Sydney eSIM plans
Sydney Airport is 13 minutes from Central on the Airport Link train, tapped with your phone at the gate, and the eSIM is on before the queue at the SIM counter, which needs a passport by law. Telstra, Optus and Vodafone cover the city, the harbour and the Blue Mountains line with 5G.
The cheapest Sydney eSIM is $1.10 for 500 MB · 7 days; unlimited data costs $1.38 a day (the first 500 MB each day at high speed, then 512 Kbps under the fair use policy). Plans run on Optus and Telstra, with 5G. Prices checked 9 November 2026.

Sydney eSIM questions
How much does an eSIM for Sydney cost?
Plans start at $1.10 for 500 MB · 7 days. Unlimited daily data costs $1.38 a day (the first 500 MB each day at high speed, then 512 Kbps under the fair use policy). Prices are in US dollars and include everything: no roaming fees, no subscription.
Does the eSIM work on Sydney trains and in the harbour tunnels?
Yes. The city rail tunnels and the harbour tunnel have coverage on all three operators, and the ferries and light rail are above ground.
Can I use it for Melbourne, Cairns and Uluru?
Yes. An Australia plan covers the whole country; pick a Telstra plan for the Outback and Far North Queensland, where the other networks thin out.
