The Suns could be willing to offer pick 5 in the upcoming draft for the Magpies midfielder, who has expressed his desire to remain at the Holden Centre for 2021.
The Magpies are battling for salary cap space as they look to lock away star forward Jordan De Goey to a two-year deal.
A potential move north for Treloar would open up significant salary space for Collingwood and would end a number of lingering list issues at the club.
Treloar’s partner and Netball star Kimmy Ravaillion will move to Queensland for her career.
The Suns are chasing their first finals berth in their existence, hoping to add some experienced talent to boost their chances of a top eight finish.
