England have cruised to a 41-5 win over the Wallaroos in wet and wild conditions in Auckland
Jay Tregonning's side were unable to match the dominant England pack as they controlled the contest from the opening whistle.
They raced out to a 19-0 before some great hands put Emily Chancellor over in the corner for the Australians.
The Red Roses have won their last 28 games and showed their class to close out the game, with all seven tries coming via the forward pack.
They join New Zealand and France in the final four after their wins over Wales and Italy respectively, set to play either Canada or USA.
Both teams were met with conditions more befitting snorkelling gear as the rain pelted down at Waitakere Stadium.
The world number one Red Roses looked to establish their dominance early as their scrum dominated their counterparts.
This allowed captain Sarah Hunter to dive over from the back of a 5-metre scrum in her 138th game, breaking the record for most International caps by an English International.
The Wallaroos were given a chance to strike when reigning World Rugby player of the year Zoe Aldcroft was yellow-carded for a dangerous cleanout on Georgina Friedrichs.
Lori Cramer took the chance to try and add first points via a 45 metre penalty attempt, falling short in the torrid conditions.
England continued to build pressure as the Wallaroos held strong, repelling waves of attack.
Captain Shannon Parry found herself sitting down for ten after too many penalties on their line, opening the door for Marlie Packer to cross via the rolling maul.
They extended their lead via Packer's second, having been denied minutes earlier by some great scramble defence.
Needing a spark, the Wallaroos brought the Auckland crowd alive with a great display of running Rugby.
Liz Patu broke through the line with a great run before her offload found Grace Hamilton, with some lovely hands from the number eight and Sharni Williams putting Emily Chancellor in on the siren.
This awoke England, with Abbie Ward barging her way over the line after initially appearing to be held on.
Cokayne then crossed for her second after peeling off the back of the maul and finding space.
The Wallaroos' defence refused to give up and found a way to deny further try-scoring opportunities.
With conditions improving by the minute, England looked to send a statement as Alex Matthews added to the advantage.
Packer added her third as the siren sounded to seal an emphatic victory for England
