Currently signed to Bristol Bears in England, 29-year-old Morahan rejoined the Australian squad for a trial week as they prepare for this weekend's Sydney Sevens.

A Super Rugby championship winner with the Reds in 2011, Morahan was also a member of the Australian Sevens team that won the silver medal at 2010 Commonwealth Games in Delhi.

"We've been in talks with Luke Morahan for a while and he has talked with great passion about playing for Australia again, especially at the Olympic Games," said Australian team coach Tim Walsh.

"Luke is a great athlete with a smart Rugby brain and is well suited to the versatility of Sevens Rugby.

"Bristol have been very supportive of allowing Luke to step away and chase something that he really wants to do and we thank the club for making him available for this week."

Three-Test winger Morahan said he'd been thinking for a long time about a chance to represent his country again.

"This week is really about a fact-finding mission to see if its going to potentially work out for both parties and I've been impressed with what I've seen from the group just today.

"It's really going to the case of hitting the ground running with a lot to take in but I'm looking forward to getting into the hard work."
