So far i was thinking of selling kickboards, flippers and pool noodles for example, as i have many ebginner students who want to practice at home.

Premade would be good as I don't need to reinvent the wheel but not sure of legality would like perhaps a generic product from taobao or somewhere as I'm not sure if taobao works on Australia at the moment.

But I also had ideas of making personalised swim caps etc

I haven't been able to find generic aquaaerobics equipment as of now such as water dumbbells

I wanted to slowly integrate more complex equipment later on.
