Hens party ideas

I'm looking for some Ideas for a hens night? Im in charge of organising the besties hens party, so far I have booked a pamper treatment day ( where the guests will be able to choose either a mani or pedi) with champagne nibblies etc., ( around 6hrs the beauticians will be with us as there's ten girls to do treatments on ) I was looking at ideas for what to do for the rest of the night
( I'm located in Qld) after the pamper something fun to continue the night on ., does anyone have any good suggestions on what else I could do ?
