But the win for the world number one ranked side didn’t come easy under the scorching sun of Port Moresby.
The Australians were clinical in the first half, putting on 30 points on a side that was making their first international debut.
Despite running in two early tries, it wasn’t all perfect in the second half for the Jillaroos with passages of scrappy play.
This allowed the home side to put some sets together and build up pressure inside their opponent’s half.
The highpoint of the match came in the 66th minute when a short ball from Shirley Joe to prop Maima Wei allowed her to barge her way over the line to score, and in doing so became PNG’s first female try scorer in an international.
The last quarter of the match belonged to the Orchids who defended their try line and denied the visitors any more points.
