Andrew John Harrison was born on 7 June 1987 in Bayswater North, Victoria.[3][4][5][6] At the age of seventeen, he became a quadriplegic as a result of a 2004 diving accident when he jumped head first into a shallow river. He spent time recovering and undergoing physical therapy at Kew'sRoyal Talbot Rehabilitation Centre.[4][7] His accident is one of the reasons he was part of a campaign called "Don’t Drink and Dive" which encouraged people to be careful when diving.[7] His hobbies include four-wheelers, cars and off-road buggies, which he can drive despite his injuries.[3][4][8] As of 2021[update], he lives in Bayswater North, Victoria,[8] is a student[4] and works as a Spinchat Coordinator.[5] He is married to Lisa and they have a son Jack who was born on 1 January 2015.
While Harrison was rehabilitating following his accident, he was visited by a member of the national wheelchair rugby team who encouraged him to try the sport.[4] He made his first Victorian state representative team in 2006, not long after his accident. That year, his Victorian side finished third in the National Wheelchair Rugby League and he was named the rookie of the year. In 2009, he played for the West Coast Enforcers and finished the season being named to the league's all star four. He changed teams and played for Victorian Thunder in 2010, and was again named to the league's all star four. He was with the Victorian side again in 2012.[4][5][9][10][11]
The first time Harrison was invited to a national team training camp was in 2007.[4] He then went on to play in an international match against the New Zealand national wheelchair rugby team that year at the Oceania Regional Championships.[3][5] While he was considered for the 2008 Summer Paralympics, he was ultimately not selected.[4] Following this brief appearance, he did not make the national team again until 2010 when he was a member of the team at the Four Nations Tournament.[3] That year, he was also a member of the Australian team that competed at the World Championships.[4] Wearing jersey number 15, he represented Australia at the 2012 Canada Cup.[8] In May 2012, he participated in a test series against Japan in Sydney.[12] He scored four goals in the fourth game which Australia won 47 – 44, and two goals in the fifth game where Australia won 61 – 55.[13] He was selected to represent Australia at the 2012 Summer Paralympics in wheelchair rugby.[3] Going into London, his team was ranked second in the world behind the United States.[14] He was part of the team that won the gold medal.[15] The Australian team went through the five-day tournament undefeated.[16]
He was a member of the team that retained its gold medal at the 2016 Rio Paralympics after defeating the United States 59–58 in the final.[17]
In 2020, he is the captain of the Power House Wheelchair Rugby Club in Victoria.[19]
