Keep your eyes open at Target (also Target Country) Today i had a look and my local TC has the Celestia and Luna sets. They hadnt finished setup yet but there will be plenty more ponies (2 bays set aside - which is impressive considering its a TC store).
Also Fashion style Celestia+ Luna sets found in another regional Target store.
So a heads up to anyone who missed out on getting them
EDIT:
A trip to Kmart today sure gave me a surprise. Wave 2 of Glimmer wings have turned up, Daisy Dreams and Fluttershy!
Also, Kmart have appeared to skip wave 3 entirely and they now have wave 4.
Australian pony distribution is really confusing. wow.
