We decided on Darwin as our point of exit from Australia. From here we can ship to Dili, Timor-Leste or to Singapore and bypass Indonesia. For us this was an easy decision, we'd ship the car to Dili and island hop our way through Indonesia using the local RORO ferries. I've put together a bit of a summary of costs and timings below.
Darwin to Dili
Agent: Bollore
Cost: AUD2855 paid to Bollore in Darwin and a further USD225 paid to Bollore in Dili
Timing: The shipping runs approx. every 10 days with the voyage taking 2 days.
We experienced delays both in Darwin and in Dili and ended up being without the car for a total of 13 days.
