[1] Green was awarded a scholarship to the Australian Institute of Sport in 1998,[2] and won a bronze medal at the Liverpool International Boxing Tournament in the same year.

[1] At the 2000 Australian National titles in Broadbeach, Green lost a "furious contest" against Victorian Nathan Woodham (a boxer he would go on to beat twice in his professional career).

[1] Green fought in the 81 kg (179 lb) division at the Olympic Games,[4] and beat the Brazilian Laudelino Barros with a "referee stopped contest" decision in the fourth round of his first bout.

[4][5] In his second bout, Green was defeated by the Russian Alexander Lebziak – also by a "referee stopped contest" decision in the fourth round.

[4] In 2010 Green described Lebziak as his toughest opponent, stating "he was a Russian general in the military, nicknamed 'The Animal' and he had a head impervious to punishment.

[9][10] Following the 2000 Olympics, Green turned professional under trainer-manager Jeff Fenech,[1] and began training at the Bankstown Police and Community Youth Club from March 2001.

[15] On 29 September 2004 Green survived a second-round knock-down (the first of his professional career) to beat Argentine Omar Eduardo Gonzales in Sydney.

[16] In the fifth round, a cut over Gonzales' right eye was ruled too severe to continue, and as Green was ahead on two cards (whilst drawn on the third) he was awarded the win.

"[17] Green's Perth-based manager Wayne Loxley said "We must move forward after tonight's fight, ... We'll offer $2 million to bring Markus Beyer to Perth.

[22] As a precursor to their meeting, both boxers had bouts on the same card in Perth on 11 December 2005 (Green defeated Garcia and Mundine stopped Rico Chong Nee in three rounds).

[25] Following his loss to Mundine, Green moved up to the light-heavyweight class to fight fellow Australian Jason DeLisle in Perth on 21 September 2006.

[26] On 21 January 2007 Green met Paul Murdoch in a Pan Asian Boxing Association light-heavyweight bout at the State Netball and Hockey Centre in Melbourne.

[30] Having "prodigious reach", being 1.96 m (6 ft 5 in) tall, and "having lost only one of 33 fights before winning the title against Italian Silvio Branco in April", Drews was considered one of the most awkward boxers in the world.

"[32] Green's retirement from boxing ended when he met South African Anthony van Niekerk in Perth for a light-heavyweight bout on 26 April 2009.

"[33] Green met Argentine Julio Cesar Dominguez for an IBO cruiserweight world title fight in Mississippi, US on 16 August 2009.

[35] Green knocked Dominguez to the canvas twice in the fifth round – the second of which prompted his corner to throw in the towel as their fighter "lay dazed on the floor".

[35] On 2 December 2009 Green placed his IBO cruiserweight title on the line and fought eight-time world champion American Roy Jones Jr. at the Acer Arena in Sydney.

[36] Green dropped Jones with a right punch midway through the first round, and then "pummelled the American legend with a flurry of blows against the ropes" – causing the English referee Howard Foster to halt the contest two minutes and two seconds into the bout.

[40] Between the Jones and Briggs fights, Green defended his IBO cruiserweight title when he defeated the Puerto Rican Manny Siaca by a third-round KO in Perth on 14 April 2010.

"[44] The incident received criticism from many boxing experts, with some comparing it to the controversial Bruce Seldon vs. Mike Tyson bout from 1996[44] and the Western Australian Professional Combat Sports Commission (WAPCSC) launched an enquiry into the fight.

[47] The contest was described as "hard-fought" and despite being "forced on the back foot for much of the fight", Green won the twelve round bout by a unanimous points decision.

[49] On 20 July 2011 Green met American Antonio Tarver (nicknamed the "Magic Man"[50]) for an IBO cruiserweight title bout at the Entertainment Centre in Sydney.

"[51] Green met the Polish fighter Krzysztof Włodarczyk (nicknamed "El Diablo") in Perth on 30 November 2011 for a WBC cruiserweight title bout.

[53] Green started the fight strongly with commentators estimating that he won the first six rounds – whilst stating that Włodarczyk "didn't appear all that shaken up by the onslaught.

"[52] Green held a press conference on 2 December 2011 at which he refused to rule out retirement; stating "Age means nothing, it's up to individuals" and "I would like to walk away saying that I can still beat the best.

Two weigh in events were held within one day, carefully planned by the Green promotion team to aid in weight draining Cameron and ensuring he was not able to re-hydrate to a decent level.

His father was born in Burracoppin as one of eleven children; he left school at the age of 15 and farmed sheep and wheat in the rural Wheatbelt locality of Warralakin.

[68] Green's father eventually moved the family to Perth "after yet another bad season",[1] where he worked as a manager for Hungry Jack's and coached junior Australian rules football.

[72] In late 2014, Green partnered with business associate Tim West, to launch a new Boxing Gym, called UBX Training (Formally known as 12 Round Fitness).

The brand has a multinational presence[73] and leverages several smart wearable technologies such as MyZone, encouraging members to proactively monitor and track their progress.
