We did west to east 2 years ago and found the most valuable info was in John Knights Cruising NT Coast book. Particularly the info on tides - the tidal caluclator was invaluable for getting it right. There's another little known cruising book by Leslie Richards - Cairns 2 Darwin, a cruising guide to northern
Australia. I got my copy from Niblock Publishing but Im not sure if its still in print.
