David Walsh

David Dominic Walsh (born 1961 ) is an Australian professional gambler, art collector and businessman.

He is the owner of the Museum of Old and New Art (MONA) and Moorilla Estate.

Walsh grew up in a Roman Catholic family in the Glenorchy district of Hobart, Tasmania, Australia, the youngest of three children.

He attended Dominic College, and the University of Tasmania, where he briefly studied mathematics and computer science in 1979.

Walsh made his fortune by developing a gambling system used to bet on horse racing and other sports.

Walsh describes himself as a "rabid atheist".

In 2001, he founded the Moorilla Museum of Antiquities on the Berriedale peninsula in Hobart, which closed in 2007 to undergo $75 million renovations.

In 2009, Walsh and his syndicate reportedly won $16–17 million over the Melbourne Cup Carnival.

It was re-opened in January 2011 as the Museum of Old and New Art or MONA.

MONA won the 2012 Australian Tourism Award for best new development and is a major Tasmanian tourist attraction.

In July 2012, Walsh was involved in a dispute with the Australian Tax Office, which demanded he pay $37 million from the profits of his gambling system.

He has been married twice, the second time in March 2014, to artist Kirsha Kaechele.

He has three children from different relationships.

In October 2014 Walsh's book A Bone of Fact was published.

The publisher described it as Walsh's "utterly unconventional and absorbing memoir".

On 20 July 2015 Walsh's partner Kirsha Kaechele gave birth to their child Sunday Walsh.

In the 2016 Australia Day Honours, Walsh was made an Officer of the Order of Australia (AO) for 'distinguished service to the visual arts through the establishment of MONA, and as a supporter of cultural, charitable, sporting and education groups.'
