North Melbourne is reportedly interested in Calrton defender Zach Tuohy.
Fox Footy's Jake Niall reports that the Roos are one of a number of clubs keeping close tabs on the Irishman, who is yet to commit to Calrton.
Thohy is said to have received a two-year contract offer to remain at the Blues, but has also received an offer to join North Melbourne.
He is not a free agent and the Roos would therefore have to facilitate a trade with Carlton to secure the 26-year-old running backman.
The 120-game player was recruited with pick 73 in the 2010 Rookie Draft.
