Hartlett, who is contracted until 2020, is understood to be open to a trade after a disappointing year at the Power, according to the Herald Sun.
The Suns have also shown interest in Hartlett, however, he is believed to prefer a move to a Victorian club if he does leave Alberton.
Port Adelaide is also reportedly open to parting ways with Hartlett in order to regenerate their under performing list.
The Power will demand at least a high first round selection for Hartlett, after rejecting an offer of two first round picks for the former top-five selection last year.
The 26-year-old was selected with pick No.4 in the 2008 National Draft and has played 127 games with the Power in eight seasons.
He averaged 18.2 disposals, 6.7 contested possessions, 4.1 marks, 4.5 tackles, 2.5 inside 50s and 3.9 score involvements per game in 2016.
