An Australian international and New South Wales State of Origin representative prop, Lazarus won premierships with the Canberra Raiders, Brisbane Broncos and Melbourne Storm, who he also captained.

He quit PUP on 13 March 2015 citing issues with its leader Clive Palmer, and established his own political party, the Glenn Lazarus Team.

[4] In June 2021, Lazarus was awarded the Medal of the Order of Australia in the 2021 Queen's Birthday Honours for "service to rugby league".

Lazarus achieved a formidable reputation in prop forward position at club, state (NSW), and international levels.

He was the first player in the history of the game to win premierships with three clubs: Canberra Raiders, Brisbane Broncos and Melbourne Storm.

Lazarus began his first-grade career with the Canberra Raiders in 1987, and was selected to make his debut for New South Wales in the 1989 State of Origin series.

In the summer preceding the 1992 season, Lazarus was recruited from Canberra by his former coach at the Raiders, Wayne Bennett[6] and joined the Brisbane Broncos, with whom he played the largest portion of his career.

He played for the Broncos at prop forward in the 1992 grand final victory over the St. George Dragons, following which he travelled with the Broncos to England, where he played at prop forward in the 1992 World Club Challenge against British champions Wigan, helping Brisbane become the first NSWRL club to win the match in Britain.

He then played for Australia at prop forward in the World Cup final victory over Great Britain at Wembley Stadium.

[7] During the 1994 NSWRL season, Lazarus played at prop forward for defending premiers Brisbane when they hosted British champions Wigan for the 1994 World Club Challenge and lost.

It was only a broken (dislocated) ankle suffered during a 1997 World Club Championship match that prevented Lazarus from playing in that year's Super League grand-final-winning Brisbane side.

In 2000, Lazarus was awarded the Australian Sports Medal for his contribution to Australia's international standing in rugby league.
