The junior Bombers' mentor was awarded the title after being nominated as one of the coaches of the month throughout the season.
He will also receive a $500 voucher for Sporties Barooga alongside the gong.
"It's pretty special, I was pretty surprised at first. But obviously I'm very happy to win it, it's an honour," Trower said when accepting the award.
"It's a volunteer job, you're not doing it to win awards. It's a reflection of our club and what we've been able to achieve, it's not just me coaching the kids or helping out, it's everyone at the club."
Trower got into coaching when his younger brother's side needed someone to shuffle the magnets.
"I had (my) little brother playing in the under-14s out at Waaia and we needed someone to coach and I was happy to put my hand up to do it," he said.
"Probably more because I was available at first to do it all the time with training and game day starting early and all of that sort of stuff.
"He's played right through to this year and I think I've sort of gained a bit of confidence and I've started to like it more and more each year as I've done it over the last couple of years.
"Now I'm really starting to enjoy it and get something out of it, not only for myself, but for the kids that are doing it as well."
Trower credited the Waaia community for providing a solid platform for the football-netball club to be successful on and off the field.
"We're only a really, really small town out at Waaia, only with about 100-200 people living in it, if that," Trower said.
"We're able to get people in from the towns around, but when we come to Waaia we're really close together, a tight-knit group, whether that be from the under-14s right through to the seniors in the football or in the netball.
"It's all joined together and we've provided ways out at Waaia to connect the under-14s, 17s, reserves and seniors all together to make our club really family friendly.
"It's good to be out there, everyone enjoys going to training and to games, everyone's happy to help out with whatever they need to do to ensure the club keeps going and keeps improving, especially with this COVID stuff, I think volunteers and that sort of stuff has increased by a lot."
One of the key pillars implemented at the club has been a buddy system to help attract, develop and retain junior players.
"Over the last couple of years we've developed a bit of a buddy system in the football and I think the netball are doing it too," Trower said.
"We've been able to have a buddy system between our 14s and senior group, for instance we match a junior player up with a senior player where they get to train with them and chat with them outside of training and all that sort of stuff.
"On game day the juniors can run out in front of the seniors before they run out to play, but this buddy system that we've been doing for a few years now is really working well and helping to keep people at the club.
"It gives the kids a chance to see what happens as you go through the club right from juniors all the way through to seniors.
"You can see the kids walk a bit taller (when they're talking to the senior footballers).
"It's been really successful in terms of getting juniors to the club and keeping them at the club."
