Flynn was recruited by the Power last year as an international rookie after impressing at the NAB AFL Draft Combine, and trained with the club throughout the pre-season.
He played his first AFL game in February during the NAB Challenge, but in March he headed home to be with his terminally ill grandfather, who died shortly after Flynn left Australia.
Flynn also struggled with homesickness, but has kept in touch with Port Adelaide and is keen to get back into things at Alberton Oval.
"They're giving me loads of time but I think I'm going to go back [to Australia]," Flynn told AFL.com.au.
"I'd like to go back, but I still have a couple of things to sort out with the club. It's just a matter of seeing where things are at and coming to some sort of arrangement."
Flynn trained this week with the European Legion, a group of 26 players from across Europe coached by Tadhg Kennelly. They played against the travelling AIS-AFL Academy on Saturday in London, losing by 95 points.
Although he suggested his skills were rusty after a month without having a kick of the Sherrin, Flynn was a standout for the Legion with penetrating runs through the middle of the ground, some bursts of speed out of packs and skillful kicking.
He said being around the team this week had reignited his passion for the Australian game.
"I've been thinking about it for the last couple of weeks and I love playing the game. It hasn't turned me off it at all – it's convinced me a little bit that I really like it," he said.
Flynn has followed the progress of the Power from afar, and this week caught up with the club's recruiting manager Geoff Parker, who is one of 18 AFL club recruiters on the Academy's tour.
He said the Power had been supportive during his difficult personal circumstances.
"I was very close with [my grandfather] and he was always very good to me. Him being sick was just the straw that broke the camel's back. Everything just got too much and I had to go home for a little while," Flynn said.
"He passed away and I wanted to be in Ireland with my family."
Flynn's younger brother Luke was also a part of the European squad, which included players from Ireland, Croatia, Denmark, England, Germany and Sweden.
Irishman Sean Hurley, who is set to join Fremantle at the end of the year, also played on Saturday.
