Sydney and Great Barrier Reef packing list for families
A Sydney and reef trip covers two very different climates, from a cool harbour city to the warm tropics up north. Packing for both, plus reef-ready gear for kids, keeps the long trip comfortable.

Kristina's notes on Sydney & Great Barrier Reef
- US citizens need an Electronic Travel Authority (ETA) to visit Australia, applied for through the official Australian ETA app. Take care of it as soon as your flights are booked.
- Stinger season in tropical Queensland runs roughly November through May. Reef tours provide stinger suits, but I pack a kid-size one because rental sizes often run large.
- Sydney and the reef are different climates. In July, Sydney can be jacket weather while Cairns is warm and sunny, so pack in layers for both.
