Gallian moved to Trent Bridge as captain in 1998 after eight seasons with Lancashire, and in 2004 led them to promotion in both the Championship and National League. A former Australia Under-19 captain, he played three Tests for England while at Old Trafford.
"Jason has enjoyed an outstanding season in 2004 and as he was born in Australia, it is fitting that he should receive a benefit in an Ashes tour year," explained David Collier, Nottinghamshire's chief executive. "He has given outstanding service to both Nottinghamshire and to English cricket and we wish him every success in this well deserved benefit year."
"I wish to thank the club for awarding me this honour," Gallian said. "It caps a most enjoyable season and I look forward to an equally successful summer during my benefit year in 2005."
