I went to Oz-Comiccon today, and was surprised to see stacks of Transformers gear. alternate a Worlds had stacks of Roadbuster and Tankor, while a new store called ToysNkdownundet.com.au had heaps of Encore releases, Mp Prowl and Smokescreen, Starscream etc. I guess they must be related to ToysNK but their website didn't have the same range as at the show.
Also saw a new toy store, Comicbookheroes.com.au that happened up at Aspley.
Shop 2, 1355 Gympie Road, Aspley. The flyer listed Transformers, but they didn't seem to have any for sale at the show.
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
