As a professional rugby league player, Glenn Lazarus achieved some of the most significant accolades ever achieved of any player in the game. Glenn began his first grade career with the Canberra Raiders in 1987 and quickly became a key player at the club playing a starring role in the club’s premiership victories over the Balmain Tigers in 1989 and the Penrith Panthers in 1990. At the end of the 1990 rugby league season, he went on the 1990 Kangaroo tour of Great Britain and France.

In the 1992 season, Glenn was recruited from the Canberra Raiders by his former coach at the Canberra Raiders, Wayne Bennett and joined the Brisbane Broncos. He won two more premierships with the Brisbane Broncos in 1992 and 1993. This constituted a remarkable feat of playing in consecutive grand finals for five seasons. In fact, it was only a broken leg suffered during a World Club Championship match in 1997 that prevented Glenn from also playing in that year’s premiership-winning Brisbane Broncos side as well.

In 1997, Glenn was recruited to the newly established Melbourne Storm and named as the club’s first captain. He went on to win another premiership with the Melbourne Storm in 1999. Glenn announced his retirement from the game with five premierships for three different clubs (Canberra 1989–90, Brisbane 1992–93 and Melbourne 1999), a truly unique achievement. Glenn is the only player in the history of the game to win grand finals with three different clubs.

Glenn played 22 matches for New South Wales in State of Origin between 1989 and 1999, scoring two tries. Glenn was known for his powerful, relentless charges and was the first prop chosen for any NSW State of Origin side.

He was selected for the 1990 and 1994 Kangaroo tours and named Players’ Player for both tours. During the 1992 Great Britain Lions tour of Australia and New Zealand, Glenn helped Australia retain The Ashes. Opposing Great Britain and New Zealand sides regard Glenn as unmatched as a forward. It is widely recognised that Glenn is one of the best props of the modern era.

In 2000, Glenn was awarded the Australian Sports Medal for his contribution to Australia’s international standing in rugby league. In 2003, he was one of the first former players inducted into the Brisbane Broncos official Hall of Fame. In 2005, the western grandstand of Olympic Park Stadium was named the Glenn Lazarus stand in his honour.

In February 2008, Glenn was named in the list of Australia’s 100 Greatest Players (1908–2007) which was commissioned by the NRL and ARL to celebrate the code’s centenary year in Australia. In 2008 New South Wales announced their rugby league team of the century, naming Glenn at prop. In June 2021, Glenn was inducted into the NSW Rugby League Hall of Fame.
