I'm only writing this only on the price of a quote - I didn't go on to use the service, due to the price - but I thought it worth posting the price, so other people can shop around.

I obtained a quote to send my computer from Hobart to Melbourne - for packaging alone (which I requested as a separate quote) they quoted $95, for packaging plus delivery, $240.

Granted, their packaging with foam-in-place was seriously impressive, and for computers or other electronics, you might be happy to pay that - it amounted to one quarter of my trade-in value, so I didn't.
This also meant the fee for service, over and above the packaging costs, was $145. I obtained exactly the same service (insured, same delivery time, same parcel, same weight) from FastWay for $39. So you might want to shop around. . . .
