Harding claimed the competition's highest individual honour with 26 votes, ahead of Western United star Chloe Logarzo (21) and Sydney FC jet Cortnee Vine (20).
The 24-year-old forward notched 12 goals and four assists for the Wanderers, setting a club record for most goals in a season.
Harding's exploits also earned her a first Matildas call-up in February.
She was presented with the Julie Dolan Medal at halftime of Saturday's grand final between Melbourne City and Sydney FC at AAMI Park, after the Australian Professional Leagues opted not to hold an awards night.

"I actually like did not even think I was gonna get this award, I was just standing there like 'why am I actually standing here?'" a shaking Harding told reporters after receiving the medal.
"Like I thought maybe I was getting joint goal of the season or something.
"I did not think I would ever even in my wildest dreams be getting this award. So it's crazy.
"Unreal. So many things have come together for me this year on and off the pitch.
"I've had so many good opportunities and I've just really made people around me proud which I'm so happy about and to get this honour has just topped it off."
Harding paid tribute to her late father after winning the award.
"That's why I started crying up there because honestly, this whole season he's just been in the back of my head," she said.
"I've just been wanting to make him proud and I honestly like think he would just be so proud up above right now.
"It just makes me so emotional to think about it, but I'm just so grateful."
