The Melbourne City striker has back-to-back golden boots and three-straight premierships in her possession and a World Cup in her sights with the Matildas.
But there is one big prize that still eludes the lethal McNamara -- an A-League Women championship.
McNamara, 23, was concussed early in City's semi-final loss to eventual champions Central Coast last year and injured when Sydney upset the premiers in 2024.
"It's the one thing that's gotten away from us," McNamara told AAP.
"Especially the past few years, we've got that premiership, but we know how important this championship is, in Australia especially.
"So it's going to be tough, but we're so hungry."
Standing in City's way first are arch-rivals Melbourne Victory in the two-legged semi-final, starting with Saturday's first game at AAMI Park.
McNamara has 12 goals and five assists and knows her match-up against Victory skipper Kayla Morrison is pivotal to City's hopes of progression.
"I've got to try and find new ways, because she's kind of getting me on the last few occasions," McNamara joked.
"If you want to be the best and be the champions at the end of the year, you've got to play against the best, and they are one of the best.
"It's always a tough challenge, especially against Kayla, but I think we both love the challenge."
McNamara missed out on contending for the 2023 World Cup through injury and has plenty of motivation to maintain her form: next year's tournament.
"It's huge, especially being Brazil - the home of football, a totally different experience probably to the last World Cup in Australia," McNamara said.
"It's the pinnacle of football, whoever you are, it's super exciting. Hopefully, I can be there, but I just want to put my best foot forward for that moment and then see what happens.
"I'm trying to learn off the best.
"You've got Sam (Kerr), who's back in now, and she's the best of the best pretty much in terms of strikers, so getting as much learning as I can off her is really what I'm trying to do."
Come season's end, McNamara is open to a move overseas, provided the right club comes in at the right time.
Recent Matildas debutant Leticia McKenna is also among City players certain to attract interest, meaning it could be this group's last shot at a championship.
"There's a few of us who have been here four or five years now who really want to get that championship," McNamara said.
"It's huge for us this year and we've put ourselves in the best position that we can."
