It is understood Gold Coast and Brisbane have been sounded out over their willingness to sign Barba from the Bulldogs in 2014.
Although officials from all three clubs were on Monday tight-lipped about the negotiations, the move north will only stand a chance if Canterbury-Bankstown convince Israel Folau to return to rugby league.
Gold Coast CEO David May on Monday night denied any knowledge of his club being approached, with his Bulldogs counterpart Todd Greenberg giving the same answer.
Brisbane chief executive Paul White and recruitment manager Andrew Gee did not return calls.
With Folau tipped to command in excess of $750,000-a-season, the Bulldogs cannot accommodate both him and Barba under the salary cap.
