I only found out about this tonight at work, and not much is known about this, as it was just a small advertisement in today's paper.

It said a store (not named) was closing down in Geebung, and was liquidating their toy stock... and named several example toy brands (including Transformers).

If it is a Toyworld, or some other independent, it might have a few old oddities still lying around... but being an Australian toystore, I doubt there would be anything new or unique.
Or it could be a wholesaler closing down, which would mean cases of toys (but still nothing that hasn't been released here).

If the pricing is discounted enough, it might be worth buying up a few things to use later as trading stock, or to resell down the track when they are worth more.

The details:
Address - 105 Baslat St, Geebung
Time/Days - 9am-2pm, Saturday 25th & Sunday 26th August

I'll try to get over to it to see what it has on offer.
