I'm pretty sure closed shoes are a must in NSW...
Law compells nothing other than helmet. You can ride in ballet shoes and a tutu as long as you've got an AS1698 helmet on.
Might attract the cops though (they like tutus)
I have a scar on the palm of my hand to this day from a) not wearing gloves b) thinking it wont happen here.
I had arrived at Broadford for a road race, unloaded the bike and also unloaded a mini pit bike. After getting all organised I jumped on the pit bke to go to sign up - no helmet no gloves. After sign up I am riding back and see a mate and decide that he should witness my expertise!! So I pull a mono on this evil little fucker and..flip the bike

. Suitably embarassed and taking major humiliation from all "mates" I look at my (by now) sore hand a its pretty bloody with a big flap of skin hanging open (fuck fuck fuck fuck fuck). No track riding fo me that day so 40 minutes after arrival I load the bikes back on the trailer and off to hospital for 15 stitches.
All caused by a ten minute ride on a jr50 Suzuki and a "what could possibly go wrong?" attitude to gloves.
