Hasleby grew up playing football in Northampton, a small town 470 km north of Perth.
He moved to Perth to attend secondary school at Mazenod College where he played football, cricket and tennis.
In 2003, Dwayne Russell raised concerns that Fremantle had been happy to lose the final game of 1999 to ensure that they received the priority pick.
[1] Fremantle deny that they did not try to win the game, instead blaming injuries and an inexperienced team for their poor performance.
However, Hasleby did not miss a game between 2002 and 2005, despite suffering at times from a hernia-like injury during the 2005 season,[2] and he won three Glendinning–Allan Medals in three years.
