Hi,
I was looking for a full frame 70-300 telezoom for my Nikon with optical image stabilisation and found this
Tamron AF 70-300mm f/4-5.6 SP Di VC - $449 at Digital Camera Warehouse.
Digidirect has it for $499.
Seems like a good price for Australian stock (they have it for Nikon, Canon, Sony A mounts).

DCW is currently having 10% off sale on their lenses stock + FREE SHIPPING ('Striclty while stocks last.').
I was kicking around on DCW earlier tonight, they've got the RX100 IV for a pretty reasonable price (well, relative to the RRP anyway), too, $1098:
