Brumbies Super Rugby flanker Michael Hooper looks set to leave Canberra to join the Waratahs in Sydney from next season.
The Wallabies hopeful is understood to be on the verge of closing a deal with the Waratahs even though the Brumbies and Rebels have shown their interest.
The 20-year-old's contract comes to an end at the end of this season and his departure will be a blow for the Australian Conference leaders.
Hooper was named named player of the tournament in last year's junior World Cup and has had a stand-out season so far in 2012.
His best performance to date was against the Highlanders in Round five.
A Waratahs spokesperson has refused to confirm the deal but did admit that officials were locked in a number of contract negotiations, including with players at other franchises.
"It is speculation and we don't comment on speculation," she told AAP.
Waratahs officials are also said to be in talks with back-rowers Dave Dennis and Wycliff Palu about extending their contracts.
Meanwhile, the Scotland Rugby Union have announced that a Scotland XV will play New South Wales Waratahs at the Sydney Football Stadium, Sydney, on Sunday 10 June.
