At the end of 2010 Mundy was undecided on where his future lay. At 25, the 192cm midfielder had just enjoyed his best season in the AFL.
In his seventh year at Fremantle he had won the best and fairest, he was one of the Dockers' best performed players in only the club's third finals campaign and he had been named in the All Australian 40-man squad.
But the quiet country boy from Seymour in Victoria had suitors from back home and the lure was strong.
"There was a decision to be made and there was a strong pull," Mundy said.
"Strong family ties is, I think, what has made me the person that I am."
But Mundy is sure that despite the temptations of home the decision to stay was the right one.
"At the end of the day I saw myself as a Fremantle player and I wanted to continue in that vein.
"I'm obviously stoked that I stayed and helped build a strong culture at the football club which I'm very proud of."
The 28-year-old is now a life member at Fremantle, having played 185 games, and he has become one of the centrepieces of the Dockers' destructive midfield unit.
He gathered 29 possessions in Saturday night's preliminary final win over the Sydney Swans.
Fremantle dominated the Swans' All Australian-heavy midfield, winning the clearances in emphatic fashion as it did against Geelong in the qualifying final.
"I think what makes the team work really well is that everyone knows their role within in the team - and that's for me as well," Mundy said.
"We're seeing the cohesion of the group and the continuity of the main guys go through there like myself, Nat [Fyfe], and Michael Barlow playing a fair bit of footy together, and on top of that you put Aaron Sandilands and Zac Clarke playing some really great football and giving us some silver service, which really helps."
Mundy is also embracing the fact that he is now a leader at Fremantle despite initially struggling to come to terms with that responsibility.
"I think it was just something that I needed to do to progress my football and my character a little bit.
"When I first came to the club I was a shy country lad and didn't really want to talk to anyone.
"It's something that I still don't find natural and I'm still working on day to day, week to week.
"I don't mind it. I really enjoy being in the inner sanctum of the group and helping lead the young guys."
