Cullen is tipped as Shane Warne's long-term replacement as Australia's premier slow bowler.
An offspinner who gives the ball a real tweak and crucially possesses the mystery doosra, Cullen's rise has been dramatic.
He first came to prominence in the 2003/04 season with 41 wickets for Adelaide at an average of 20.98, before capturing 17 wickets at 29.82 for South Australia in the five Australia Cup games.
Highly regarded by Aussie spin legend Warne - he has been tipped as a player for the future by many after winning a contract with South Australia in 2004/5.
Could struggle to play in the Test matches but might figure in one-day series.
Cullen has played 17 first-class matches in Australia and taken 66 wickets, taking five in an innings three times.
Bowls with aggression and flight, he includes a doosra delivery in his armoury and has signed a full Cricket Australia contract as one of the 25 centrally tied players.
He played in four county championship matches for Somerset but did not return for the latter part of the 2006 season after representing Australia A.
