Sez, I recommend Emma's Babyswim out of Ringwood Aquatic Centre, or Babyswim Australia (the parent business) in Blackburn BA is great, it's her life's research so baby swimming is her specialty, not like the big pools where baby classes seem to be an afterthought and don't have nearly as much detail to their lesson plans and goals.
Floaties Aquanappies catch EVERYTHING! Trust me, we've tested this theory
