Esperance came out victorious in the inaugural Women's Grand Final, scoring 4.2 (26) to Ports' 2.4 (16).
The Esperance girls handled the ball cleaner and moved it faster than Ports around the centre of the ground and were able to lock the ball in their forward line for long periods.
Kayesan Cox was very elusive on the wing, while the likes of Taya Neill and Nicole Fraser pushed up from the backline, won the ball in the midfield and pumped it forward.
Daisy-May Bell turned her opponents inside out with blistering pace off the half forward line and scored the opening two goals to give Esperance the perfect start.
To Ports' credit, their backline was standing up to the pressure quite well and really kept the team in the contest with some hard tackling and some good ball handling.
None were better than Jacqui Tonkin at centre half back and Kara Murphy at full back.
They received good support from Demi-Lee Barker and Sarah Callow, who were midfielders that got behind the ball and helped out.
Ports had to wait until midway through the second quarter for Robin Macale to kick their first goal, but by halftime Daisy-May Bell had kicked Esperance's third to hold a nine-point lead at the big break.
After half time, Abby Leyendekkers and Kate Maddams lifted for Ports, but Esperance always had an extra number on the outside of the packs and with quick hands balls were able to get the ball forward.
Maddie Wood, Casey Rowe and Alli McArthur got busy and Daisy-May kicked her fourth to hold a 16-point lead into the final term.
Ports were better in the last term and had some hope after Bianca Bambra scored a goal, but with Taya Neill in the thick of everything, Esperance controlled the ball enough to hold on for a memorable victory.
The umpire's awarded the best on ground to Taya Neill for Esperance and Jacqui Tonkin for Ports, with Daisy-May Bell with four goals also having an outstanding game.
