Snow established the Snow Foundation in 1990 along with his brother, George. Now valued at over A$10 million, it donates to regional charities and organisations helping needy people.
In 2005 he published the "Living City" proposal for the redevelopment of Canberra. This caused some controversy, especially after the proposal's rebuff by the ACT Government and combined with his provocative assertion that Canberra is a "dead-set boring" city that had been "going backwards since self-government".
Snow is Executive Chairman of the Capital Airport Group, the company which owns the lease for the land which contains Brindabella Business Park, Defence Establishment Fairbairn and associated Fairbairn Business Park, and the Majura Park shopping precinct. In 2013, Snow was ranked by Forbes as Australia's 39th richest person, with a net worth of $755 million.
