Jaime Chapman set a women's World Cup record with 13 tries, then scored a hat-trick as Australia beat New Zealand 34-10 in Sunday's final.
Her performance included 151 metres, six tackle-breaks and three line-breaks.
Stacey Waaka, who finished the tournament with nine tries, made 15 runs for 85 metres in the final, with two tackle-breaks.
Waaka and Kalyn Ponga had already received the women's and men's Golden Boots before the finals.
That timing drew criticism after Australia's wins, with fans arguing Chapman and Reece Walsh might have claimed the awards had voting followed the deciders.
Walsh helped Australia defeat New Zealand 32-12, setting up Tom Trbojevic's second-half try and making eight tackle-breaks and a line-break assist.
Ponga had 13 runs and four tackle-breaks, missed four tackles and made one.
He had played fewer than two full games before the final after breaking his arm in the tournament opener.
Former NRL coach Shane Flanagan said on Triple M last week: "I think it's crazy. If we're going to pick a player before this match, it could leave you with egg on your face."
One social media user wrote: "That whole Golden Boot farce went well, huh? The winners should have been Jaime Chapman and Reece Walsh, but I guess they'll just have to make do with winning the World Cup instead."
Another wrote: "The Golden Boot being awarded before the final is showing why it's a terrible decision."
