Aus Tag ( new sporting activity) in Costa Rica (San José)

I am planning to organise an activity sport called Aus Tag
it is non contact unisex , all ages sport well known in the land Down Under (Australia).
a great way to keep fit, socialise and learn a new sport that is not very well known in the Americas *outside the world of NFL or Football (soccer).* :-)
I am interested to know if anyone would be interested participating?
I am locating in Santa Ana, Costa Rica
all we need to do is find a central park to start, any feedback would be greatly appreciated.
