Hauritz, 24, who played six seasons with Queensland, is looking to rejuvenate his first-class cricket career after a virtually anonymous season with Queensland.
"Queensland has a fast bowling culture and I see this as a fantastic opportunity to go down there and work within a spin bowling culture," Hauritz said Friday.
"I still want to play for Australia and I see this as my best chance."
Hauritz took five wickets in his only Test for Australia against India in Mumbai in November 2004 including a first innings haul of 3-16 but subsequently has played just seven first-class games for Queensland.
He played only one Shield game for Queensland last championship season.
Hauritz has also played eight one-day internationals for Australia -- the last against the West Indies in May 2003 for nine ODI wickets at 34.22 with a career-best haul of 4-39.
