Time Out says

The largest island in Sydney's harbour and set at the junction of the Parramatta and Lane Cove rivers, Cockatoo Island is 18 hectares in size and named for the presence of sulphur-crested cockatoos. Before 1839, when a prison was built to house convicts from Norfolk Island, it was covered with red gums and was almost certainly an Aboriginal fishing spot.

The convicts eventually relocated to Darlinghurst Gaol and the island had a brief stint hosting an industrial school for girls and a naval training ship for boys (but due to ‘unseemly and unscheduled meetings' the girls moved to Parramatta). However, the island was mostly used for shipbuilding and repairs; its several docks serviced the Royal Navy during WWII and was the construction site of Australia's first steel warship. The island's maritime industrial activity ceased in 1992, and Cockatoo Island only opened to the public in 2007.

Today, the island is run by the Sydney Harbour Federation Trust and remains commercial free, although there are talks of reintroducing boat building on a smaller scale. The trust run different types of tours – visitors can opt for a self-guided audio tour ($6 per person) or on-demand guided tour (60 or 90 mins; $16). Those who want to stay on a bit longer also have options – there are camp sites, glamping packages, apartments or heritage holiday houses.

Sunset Sessions at Cockatoo Island

If there’s one thing Sydney does spectacularly well, it’s slow summer evenings – the kinds that see the sky turn sherbet-pink and the whole city look a little softer around the edges. This summer, Cockatoo Island/ Wareamah is handing us a very solid excuse to make the most of it: Sunset Sessions is back, taking over the lawn of historic Biloela House with a weekly dose of live music in the open air. Running on Saturday evenings from January 10 2025 to April 4 2026 (except from Saturday, March 7), the island’s curated open-air gig series is one of those annual events that reliably sells out – and for good reason. The formula is foolproof: pack a picnic rug, stretch out on the grass and let a line-up of emerging local artists soundtrack the slow fade into night as the sun sets behind the city. RELATED READ: These are the best sunset spots in Sydney This year brings a particularly juicy mix of genres and rising talent to Sydney Harbour’s largest island. Expect lush vocals from Charlie Collins, dreamy pop by Mia Lovelock, and globe-spanning grooves courtesy of Immy Owusu and Dom Diaz. You’ll also catch Bella Amor, Mina Siale, PA777IENCE, Skyscraper Stan, Lady Lyon and Lucienne – with more artists still to be announced. If you’re not the type to pack your own snacks, Biloela House will have refreshments ready to go – or you can pre-order a hamper of treats when you book your ticket. And if you’ve ever entertained the fantasy of running away to an island for the night, Cockatoo...
