The Australian Museum, the country's oldest museum (established 1827) is the custodian of 21.9 million specimens and cultural objects, including Indigenous and Pacific collections, a precious stones collection and the permanent 200 Treasures of the Australian Museum exhibition.
The Musuem reopened to the public in November 2020 after closing for 15 months for an extensive 57.5 million dollar renovation, which opened up 3,000 square metres of new public space.
Displays cover the Pacific Islands, Asia, Africa and the Americas, with items ranging from Aboriginal kids' toys to a tattooed chalk head from the Solomon Islands.
Any serious museum-tripper should see a few of the local stuffed animals, and the displays should answer all your questions about Australian mammals.
If you're interested in Aboriginal culture and beliefs, visit the Indigenous Australia section, and get informed about important issues including the Stolen Generations and deaths in custody.
Museum entry is free, however some touring exhibtions may have a cover fee.
