From TCCA on twitter, the wave 3 Leader Kingdom Galvatron toy was found at a Toyworld in Melbourne.
But don't get excited, thinking that Galvatron or any other wave 3 toys are about to hit stores in Australia, because the global release date is July 1st... and this is not a new thing in Australia.
When new stock arrives into the country, fresh from the shipping container, it sometimes gets sent out to a store before it is allowed to (if it has an global embargo date)... and for some reason Toyworld seems to be the one that ends up getting most of these "leaked" toys, and then we don't see more anywhere here until they are officially allowed to be released to retailers months later.
There must be something wrong with Hasbro Australia's inventory system, that accidentally releases stock to Toyworld as soon as it arrives, instead of when it is allowed to be sent out to retailers... and then there is a mad scramble for them to chase up the stores that got the stock, to remove any that hasn't already been sold.
Most times it is Movie gimmick toys, but when it is a highly sought after toy like this one, a small number of very lucky people get their hands on one before they are removed from sale... for a bit of online fame, or ebay fortune.
Maybe have a look around at some stores like Toyworld (especially in Melbourne), in case some others slipped out from the Hasbro warehouse before they noticed... but don't obsess too much looking for them until at least July/August.
