WA has 10 (Easter Saturday and Easter Sunday aren't included, nor is Melb Cup, but we have WA Day (used to be called Foundation Day) in June and moved the Queen's birthday to the end of Sept, in addition to the asterisked holidays above.
Adelaide have the asterisked plus Proclamation Day and the Adelaide Cup.
NSW is similar to Vic and the banks etc have an additional day.
Tassie say they have less but every region has their own Royal Show Day in addition to the Royal Hobart Regatta (or Recreation Day for the parts of the state that don't have that RHR Day off) and Easter Tuesday, as well as all of the above asterisked holidays.
I can see why they're sucking the funds out of the GST with that many public holidays, the lazy bastards!!
