I stumbled onto uShip and was hesitant at first being a US based site. Found a boat in Perth I wanted to buy online, but was concerned at the cost of shipping from Perth to Melbourne. Posted the boat and details on uShip, and within 16 hours had a very competitive quote.
3 days later, the truck pulled up at the vendor's house, loaded the boat on, helped the vendor with breaking their lock that they had lost their keys to, and giving key advice around what needed to be loaded where and what needed to be removed to avoid damage.
2.5 days later, the boat arrived in Melbourne with no damage whatsoever using CBC Interstate - I highly recommended them - small and professional - even met the driver and his family who was a great guy and told us all that he had done to protect the boat on the trip.
I would definitely recommend uShip to anyway looking for transport options in Australia, and just as highly recommend CBC. From everything I was told, this trip was almost half the price I would have got from calling up a company and asking for a price and was the difference between the boat being affordable and it not being worth it.
