Minister for Emergency Services, Minister for Corrective Services and Minister Assisting the Premier on the Arts (April 1999 and January 2001); the Attorney General, Minister for the Environment, Minister for Emergency Services, and Minister Assisting the Premier on the Arts (between June 2000 and March 2003); and the Attorney General and Minister for the Environment (between March 2003 and March 2007). Debus oversaw by far the largest ever reorganisation, expansion and re-equipment of emergency services across New South Wales. He was the longest serving environment minister in any Australian jurisdiction and oversaw the expansion of the national park system of New South Wales by over one-third .

The seat had been redistributed to cover most of his state seat; he'd represented nearly all of the reconfigured Macquarie's eastern portion at one time or another. It had previously been a safe seat for then sitting member Kerry Bartlett of the Liberal Party, but the redistribution
