The Australian Museum is the country's oldest museum, founded in 1827, with major collections in natural history, science, and First Nations cultures. It is especially strong for families, with fossils, minerals, animals, and cultural objects presented in a way that rewards both quick visits and slower wandering.
One of the classic draws is the skeleton room, where hundreds of animal skeletons are displayed, including a blue whale suspended overhead. The museum sits beside Hyde Park, making it easy to fold into a central Sydney day.
