Elliott had been originally due to play for Yorkshire until mid-May but Pakistan's World Cup elimination means Younis Khan is there from the start.

Elliott was prevented from playing a third season at Glamorgan in 2006 because of a knee injury.

He will be the fill-in for fellow Australian left-hander Jimmy Maher.

Elliott said: "People know of my affections for Glamorgan and for Wales, and I'm really looking forward to linking up with the players and getting the season off to a positive start for when Jimmy arrives."

Elliott, Australia's one-day player of the season in 2006-07, is expected to be available for the first three County Championship matches and three one-day matches too.
