Big W Burleigh Heads (Stockland) had the 7 packs of TF ooshies (no advent calendar). Its seems there are three assortments, packed 3 of each to a case.
I was bitterly disappointed to find out the 'hidden' figure in EVERY SINGLE PACK I bought was a 'common', two of which we already packed in the 7 pack. On the back it said that there were two figures only available in the 7 pack, so I assumed I'd be getting one of that. These 7 packs really aren't worth buying at $15 a piece.
Big W Woolworths had the Advent Calendars though, in a cardboard standee in the toy aisle. It had only two rows, but packed three or four deep a random assortment of Care Bears, TF, Marvel, DC. So you might be able to pick these up at your local woolies.
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
