<human>: Answer by taking a quote from the following article:

Stephen Larkham (born 29 May 1974 in Canberra) is a retired Australian rugby union footballer currently in the role of attack coach for the Australian Rugby Union side, the Wallabies. He is best known for his career with the Brumbies in Super Rugby, for whom he played from the inception of the professional Super 12 in 1996 through 2007, and his long tenure with the Wallabies at international level, for whom he played 102 times. After initial selection at fullback from 1996 to 1997, Larkham was the first-choice Australian fly-half from 1997 to 2007, playing in the 1999, 2003 and 2007 Rugby World Cups. He is married to Jacqueline and has two children, Jaimee and Tiahna.

Larkham was an important part of the Australian 2003 World Cup squad which lost in the tournament final to England. He has suffered greatly from injuries through his career, especially to his knees and right elbow. Despite these he remained a competent defender in spite of his relatively light frame. He was also tried at inside centre by John Connolly for one test against Wales 2006 but the experiment was not regarded a success and he never played there again.  He was famous for forming a long-standing half-back partnership with George Gregan, both of whom were foundation players with the ACT Brumbies rugby franchise. When both retired after the 2007 World Cup, not only were they the two most-capped Wallabies, but they played in more Tests than any other scrum-half/fly-half combination in history, with 79 appearances together. So important were they to the team that in 2007 at Bruce Stadium (Canberra Stadium), a new stand was unveiled as the "Gregan-Larkham Stand" in honour of both players and their combination to the team.  He played his last test against Japan in the 2007 World Cup before a knee injury sidelined him, which effectively ended his Test career as Australia were then knocked out of the competition before he could return.  On 14 May 2007, despite larger offers from French and English teams, Larkham signed a contract with Edinburgh Rugby in Scotland to join them after the 2007 World Cup; however; this deal subsequently fell through, reportedly because the Scottish Rugby Union would not fund the deal. Newly promoted Leeds expressed an interest, as did the Welsh side, the Dragons. However, in January 2008 it was announced that he will join Ricoh Black Rams of Japan.  Larkham played for the ACT Veterans Rugby Club at the World Vintage Rugby Carnival in Hawaii in September 2012. During this carnival he also played as a reserve for an old boys team from Brazil who, not realising who he was, asked him to play second row because he was tall. Despite his other commitments, Larkham occasionally still plays with the ACT Veterans to help them raise funds for the charities they support. On 18 February 2018, he received the GENLEC Player of the Day jacket for his great play and sportsmanship in the Clare Holland Cup charity match. CANNOTANSWER
