Sounds all good. I bipassed TI as it has security
issues. You need to anchor
over the other side and according to locals, is not safe after dark. AQIS require a 24 hour (min) notice to inspect and as such you may be waiting there for a while for them. If you try to phone
and get information from AQIS, the info you recieve can be misleading or contradictory. Customs
If you change your mind and clear out of Darwin, then dont go through TI at all as you would still have to clear AQIS. Seisia, only a few miles away is a perfct place to stop for a bit and refuel (via jerries) and food
I know the Qld section fairly well. I came back from Darwin last year.
