Myer Emporium (4th floor, entrance on lonsdale st) has 2-3 sky lynx sets complete (Sky reign and the 4 deluxe figurines)

Kmart Corio (near geelong) has Sky Reign, Onslaught and Silverbolt for the voyager, and Hound, Trailbreaker, Wheeljack, smokescreen, blastoff, brawl and swindle at the normal kmart price ($25). They have a few of the legends ones, mostly blackjack, rodimus and groove though.

Quite a few RiD and rescue bots as well, didn't have time to take down the names but I can check if you're looking for something in particular.

Myer Geelong has (had? Will confirm again tomorrow) combiner wars at roughly 25-30% off. Bought the whole destructicons set including soundwave for $130 a few weeks back. They still had then a few Onslaught and Scattershots, as well as the deluxe destructicons.
