The Hurstville Museum & Gallery building contains four exhibition galleries with a changing schedule of exhibitions throughout the year.

The Main Gallery hosts several major exhibitions each year, including travelling exhibitions. The Dragon's Lair Gallery is a community art space that can be hired by local artists and groups to showcase their work. The Snapshot Gallery is a smaller space dedicated to showcasing collections of local history photographs from the Georges River Libraries archives. Finally, there is a permanent exhibition on display, 'St George Stories: people - places - community', which explores the history of the local area.
