Just tried the Australia Post site. It came up: Product Not Trackable. May have to try ringing them tomorrow.
Have got it marked on the calendar - I can complain to ebay by the 3rd of March and PayPal by the 5th. A shame since I don't think the seller is trying to screw me, but I can't afford to shell out $25 a pop for toys that never show up so I'll have to do something. Cheers for the advice guys!
