While Fremantle has used its first selection in recent drafts to snare local midfielders Stephen Hill, Anthony Morabito and Rhys Palmer, the club this year added Victorians Jayden Pitt, Viv Michie and Josh Mellington with its three picks.
It takes the total number of Victorians recruited by Fremantle to seven at the past three national drafts, with six of the 17 new players selected by the club in that period coming from WA.
Mundy, who has twice turned down offers to return to Melbourne when out of contract, said he battled homesickness early in his career at Fremantle and he would use his experience to help his new teammates adjust to life in Perth.
"As a Victorian, with the homesickness and moving interstate, I've obviously got a fairly keen insight into that, so I'll help out where I can," Mundy said after returning to pre-season training on Monday.
The 25-year-old added that his own decision to sign a four-year deal with Fremantle in September was one of the biggest he's had to make in football and would likely tie him to the club for the rest of his career.
"It was obviously a big decision, a life decision, [and] I'll probably play out my time here now," he said.
"As a Victorian or an eastern-stater, it's a massive decision to commit to stay over here, probably for your life now. It's a big call and I didn't want to make that hastily.
"To take me through to 29 is a massive bonus when you look at the average AFL life span.
"I'm enjoying my time here and hopefully we can make the most of it."
Mundy was one of seven Fremantle players to start pre-season training on Monday, joining recruits Pitt and Mellington and the bulk of Fremantle's young list for a two-hour session that included a series of ball-movement drills and skills work.
Alex Silvagni and Michael Barlow worked in the rehab group, while delisted trio Tim Ruffles, Ben Bucovaz and Brock O'Brien continue to train with the club in the hope of being re-rookied.
Midfielders Jesse Crichton and Nat Fyfe, who are entering their second seasons, ran extensively, as did Michael Johnson.
Mundy, who was named in the All Australian squad of 40 after a standout 2010 season, said he was focused on building his fitness as he looks to continue a successful move into the midfield in 2011.
"Moving into the midfield where you've got more of the forward running and trying to exploit holes, it took a little bit to get used to," he said.
"Hopefully last year was just the start of my good form."
