Abbi Church scored four tries as Australia overcame a physical Fiji side 30-14 to reach the Women's Rugby League World Cup final.
The Jillaroos will face the Kiwi Ferns on Sunday, despite being pushed harder than in any other match of the tournament.
Fiji led early, and Australia looked untidy before Church scored in the 24th minute.
Australia's back three scored all six tries, with Tamika Upton and Jaime Chapman also crossing.
Church completed her hat-trick before a 78-metre kick return produced her fourth try as Fiji's campaign ended.
The result followed Australia's world-record 124-point win over Wales the previous week.
Australia are favourites for the final after beating New Zealand by 50 points in the World Cup decider four years ago.
However, New Zealand's power through the middle and attacking talent in the spine could challenge the Jillaroos.
Chapman left the field with what was described as cramping, but was later pictured with ice on her hamstring.
"There might be some slight concerns for Jaime Chapman. It was reported that there was some cramp, but we didn't witness any cramping," Corey Parker said on Channel 7.
Chapman told Channel 7's Jelissa Apps the substitution was "precuationary" and she would be "all good" for the final.
