Perth is hosting the event for the first time, and Pouri-Lane said her side was looking forward to it.
"The team are really pumped to start this Olympic year. A lot of the girls have family here, so we know we are going to have heaps of support and we are looking forward to getting started."
While Australia leads the series after two rounds, New Zealand shares second place with France, six points behind the Australian women, the home side wants to complete a hat-trick of titles with a win on home soil.
Australia is in a pool with Canada, Great Britain and South Africa, while New Zealand is drawn against the USA, Ireland and Japan.
Argentina leads the men's competition, and captain Santiago Alvarez said, "We are happy to have played the first two tournaments very well, but the season is very long, and we still have some things to correct.
"We are enjoying it and trying not to feel the pressure of being on top. This year is more competitive than ever; every team is very tough, and we must be very focused and keep doing what we have been doing until here."
Australian men's captain Nick Malouf said there was nothing like being able to represent his country on home soil.
Dylan Collier has returned from injury to captain the All Blacks Sevens which features experience in the form of Tim Mikkelson, Scott Curry, Regan Ware and Sione Molia.
The All Blacks Sevens, in fourth place, are in a pool with Fiji (3rd), France (8th), and Samoa (7th), while Australia (6th) meets Ireland (5th), Great Britain (11th), and the USA (10th).
