Kaos is among three local women�s teams that will compete against Australian and New Zealand teams from April 24-27.
Silver medallist and Claremont resident Geri Daube said the team was hoping to put on a solid performance but would be challenged by a couple of NSW and Victorian teams.
�We�ll definitely have the home-ground advantage because we play on those fields every week,� Daube said.
The 29-year-old has played in four nationals after taking up the sport five years ago.
There will be 12 women�s and 13 men�s teams competing over the weekend.
The City of Perth is celebrating the event by hosting a free Ultimate Film Festival in the Northbridge Piazza this Thursday from 6.30pm.
