"To be honest, probably that win sealed my decision,” she told RUGBY.com.au.

“I realised that the game's in really, really good hands and that competition I think week in, week out showed that," she added.

Hewson has had an international career which has spanned 11 years, she is the most capped Wallaroo in history and all-time points scorer.

Growing up on the NSW South Coast playing rugby with her four brothers in the backyard, Hewson never imagined her career would've been like this.

“You don't think about things like that when you're out in the back playing footy with no shoes on, so to be part of that at Allianz Stadium with that crowd and such a brutal amazing game of rugby is something that'll live in my soul forever,” she said.

She will watch on as the Wallaroos play a historic Bledisloe Cup doubleheader at ANZ Stadium in August, the first time the Wallaroos have played a home test in 10 years. 

Hewson is still committed to her Sydney Uni side but will also be seeking out coaching roles. 

“I think I'll be playing for Sydney Uni until they take me away in a coffin,” she said.

However, she hasn't ruled out playing in the Super W again and hopes to be part of it in 2019. 

“In terms of Super W, I'd love to be a part of it again next year,” Hewson said.
