Waqa, who was a member of Melbourne's 2012 premiership-winning team, will take the number of Fijians in the NRL to 23 if he can convince Storm coaching Craig Bellamy to sign him after a stint with French rugby union club, FC Grenoble.
The 31-year-old recently returned to Melbourne, where his family had been living, after breaking his jaw and was offered a training contract with the Storm.
Melbourne football director Frank Ponissi said a decision would be made on whether to sign Waqa before June 30 so he is eligible to play the remainder of the season.
