The out-of-contract hard nut is enjoying a breakout season for the Demons, averaging 27.1 disposals, 4.6 marks and 3.5 tackles.
The Kangaroos have been unable to make a big splash in free agency in recent times despite having a war chest at their disposal, last missing out on gun Magpie Jordan de Goey.
And as Brayshaw’s contract talks with Melbourne continue to drag out, the Roos are keeping a close eye on the situation and may pounce at the end of the season.
Earlier this week it was reported that North Melbourne are also targeting Port Adelaide midfielder Jared Polec.
The Demons are trying to lure off-contract Eagles running machine Andrew Gaff back to Victoria, but it is becoming increasingly likely that he will re-sign with West Coast.
Should the Dees miss out on Gaff, they will have approximately $550,000 to offer Brayshaw per year, while North have the capacity to throw a longer deal at the former pick three worth $700,000 per year.
However, if Gaff returns to his native-Victoria, the Eagles are expected to enter the race for Brayshaw too, whose brother Hamish plays for.
