The 25-year old has fallen out of favour at the Kennel this years, playing eight games and getting dropped to the VFL at various stages.
And Frawley says there is a possibility he will end up at the Lions next year.
“It’s growing by the day he might be going north (to Brisbane),” he told the AFL Nation pregame show.
“Chris Fagan would be very happy to get a player that can complement their young midfield.
“I think he needs a fresh start as well and I think Luke Beveridge would agree.
“He’s been dropped a couple of times already this year.”
Wallis is averaging 20 disposals, 5.1 tackles and three inside 50s per game in 2018.
