Kasprowicz took 60 wickets for Essex when he played for them in 1994 and a Sheffield Shield record of 64 in a season for Queensland in 1995- 96.
The Hampshire director of coaching, Tim Tremlett, said: "He will be able to join us for the start of the season. Kasprowicz is recognised as a top-class bowler and that is what we need."
The Sussex chairman, Robin Marlar, has not ruled out a move from the county's Hove headquarters in his annual report to members.
The first decision made by the committee after last year's members' revolt was to put plans to redevelop the county ground on hold - and Marlar admitted that Sussex were looking at other sights: "Whilst we develop new ideas for the county ground, we wish to see what else could be available for us."
Sussex made it clear that if a local authority backed sports complex becomes a real possibility, the club would wish to become actively involved in any discussions.Reuse content
