The club's man for all seasons will hit the milestone against Perth Glory on his 30th birthday, in a 30th meeting against the club he made his debut against back in 2006.
"I worked that out yesterday before bed and it's pretty cool," Broxham said.
"But I'll just concentrate at the job at hand and it will be a lot more enjoyable if we win the game.
"All my family will be there. I'm pretty lucky to be able to play in my hometown where my family is from. So hopefully they all enjoy it."
Broxham recalled his first game, 11 years ago this week.
"The week building up to the game I was high on emotion," he said.
"It was just before my 19th birthday and I was still kit man really.
"I remember (former coach) Ernie (Merrick) coming to me and saying 'we want to rest some players because we've won the league already and we want to take you to Perth'.
"It was pretty rewarding. And the debut went well. Kristian (Sarkies) scored a double and I made an impact coming on. It was an enjoyable moment."
Broxham's refreshing no-fuss attitude is a big reason why he'll become just the fifth man to reach the milestone in the history of the A-League - and the first for a single club.
He's played in three championship-winning seasons, under six coaches and in a variety of positions.
On Saturday at AAMI Park, he could play left-back, holding midfielder or centre-back.
And when he looks up, he'll see thousands of Leigh Broxhams looking back at him as Victory have printed a host of face-masks for the occasion.
Broxham is likely to hold the league's all-time record should he continue on for another two seasons.
Only Andrew Durante, 35, and Nikolai Topor-Stanley, 32, sit above him on the list of all-time league appearances for outfield players, with the age gap likely to see Broxham surpass them.
Durante, with 275 appearances, is likely to leapfrog goalkeeper Danny Vukovic, on 278, for the all-time lead within a month.
It's not something Broxham is focussed on.
"People say 'how you going, how many games you up to?' but I'm not counting down or looking at the list," he said.
"I'm just playing the game, enjoying it, and where I end up is where I'll end up."
