I've been searching all afternoon for a maha 8 cell smart charger and a retailer who will ship to AU.
These guys seem to be the cheapest compared to protog $101.90 delivered.
enjoy
EDIT : This will work with au supply(100v-220v) might need an adaptor to convert to au
Mod: Appears to be a legit company. Same product sold here. It is a registered business in Nebraska
they used to give a discount to whirlpool members, not sure if they still do…
