It is the largest privately funded museum in the Southern Hemisphere.MONA houses ancient, modern and contemporary art from the David Walsh collection. Noted for its central themes of sex and death, the museum has been described by Walsh as a "subversive adult Disneyland".

The precursor to MONA, the Moorilla Museum of Antiquities, was founded in 2001 by Tasmanian millionaire David Walsh. It closed on 20 May 2006 to undergo $75 million renovations. The new museum was officially opened on 21 January 2011, coinciding with the third MOFO festival.
