Since retiring from cricket in 2004, Hollioake has spent his time involved in charitable and media work as well as owning a property development business.
Hollioake was born in Melbourne in 1971 and grew up in the mining town of Ballarat, where his family had lived for five generations.
[1] His father, an engineer, had played cricket for local sides, but Hollioake showed a preference for Australian Rules Football while attending St Patrick's College, Ballarat.
He then moved to Hong Kong for 3 years, and then back to Australia, where he attended Wesley College, where his brother Ben later studied.
[1] He was described as an all-rounder with "aggressive batting and inventive medium-pace allsorts"[1] and began to share captaincy duties for Surrey with Alec Stewart in 1996.
[1] He made his test debut, playing alongside his brother Ben, against Australia in August 1997, scoring 45 runs in the first innings and taking two wickets.
[12] Other fundraising projects Hollioake has been involved in include Cricket Challenge, which raises money for the Queensland-based charity Paradise Kids,[13] where members of the public compete against stars and cricketing legends, and the Battle of the Stars charity golf day.
[14] In 2005 Hollioake took part in a revived Superstars programme on BBC television, finishing fourth in the competition behind skier Alain Baxter, Olympic athlete Du'aine Ladejo and rower Steve Williams.
[15] In 2007 Hollioake and Ladejo formed Quiet Storm Productions, which owned the television show Australia's Greatest Athlete.
[17] In 2017, Hollioake coached Afghan Twenty20 team Boost Defenders, who played in the Shpageeza Cricket League.
Later that month he revealed that he would also be fighting as a mixed martial artist in Queensland, Australia in the light heavyweight division.
For his next fight on 12 July 2013, Hollioake had a rematch against Warren Tresidder, but this time in a 6-round contest under the laws of boxing.
