Belfie - we just came back from Melb today and I noticed that just inside of T2 near the International Check in counters there is a shrink wrap service for bulky items - it costs $10 but for things like expensive prams etc, it might be money well spent. A gf of my had her Strider trashed by the virgin luggage handlers due to poor handling (eg dragging it along concrete and throwing it about while loading etc)
