But as soon as the Canberran hangs up her boots, she could be forced to pull them on once more if the GWS Giants secure their spot in the AFLW preliminary finals.

Brush is weighing up her future as a dual-code star and could be set to play her final W-League match when Sydney meet Melbourne City in the title decider on Saturday.

As she steps onto an empty stadium in Melbourne for potentially the last time, her GWS teammates will host the Demons in a semi-final clash in Sydney.

"They're going to be straight off the ground and straight onto their phones to watch the [W-League] match," Brush said.

"They're very supportive and are right behind us. I'm upset to be missing that as well, it's a big game for the Giants and I know the girls can get it done.

"It was the plan that I wouldn't play with the Giants until the soccer season finishes, and it's a big one being in the grand final this weekend."

Brush has made more than 100 W-League appearances across stints with Canberra United, Western Sydney Wanderers and Sydney.

She was part of the competition's inauguration in 2008 and won two championship with Canberra, before leaving the club to become a dual-code star in Sydney.

The 31-year-old says while it's been difficult to juggle two sports over the summer, she hasn't yet made a decision on next season.

"I"m definitely not ruling it out but it could be my last W-League game, I'm thinking about hanging up the old soccer boots," Brush said.

"This could be my third grand final win and that would be the perfect way out.

"There's other things to achieve in life, I've played 11 seasons and I'm one of the other girls now.

"I've had one of my best seasons this year, so it's definitely not a case of being too old and lost it. You always like go out on a winning high, or even making a grand final, there's no better way to do it.

"As a female professional athlete, you have to put your life on hold and make sacrifices to play at this level.

"I haven't taken a summer off for 12 years, it's a big sacrifice and you do miss out on a lot of things. So I'm thinking this could be the perfect time with family starting to take priority and becoming more important."

Sydney are gunning for back-to-back titles, which Brush admits will be a strange occasion as it will be played behind closed doors with only essential personnel in attendance.

The atmosphere given by a grand final crowd will be lost but Sydney will be spurred on by their desire to take revenge from their 2-1 loss to the star-studded City outfit in round four.

"It's time for revenge. We've come a long way since we played them in Melbourne," Brush said.

"They're a team stacked with Matildas and international players, so I think it's going to be a good challenge and one I really relish.

I feel like we're peaking at the right time and the feeling within the group is really positive.

"They've got a number of goal scorers and avenues to go all over the field, so that's something we've looked at and will have to deal with. There's threat kind of everywhere, we'll certainly have to be at our best.

"We all love playing with one another and for each other, especially with everything going on in the world right now."
