Palm Treo 680 smartphone + BONUS Bluetooth Headset! @ City Software $500
The model is a year old now so will gradually come down in price but for the moment its still current.

Delivery to Perth $17 - to Syd $16 - to Melb $10. So they'd be a Melbourne business then. Not the cheapest freight I've seen for something so small. Lucky their price is good enough.
