I would love to do one of those "mothership" trips in the Kimberley.
Comfortable accommodation onboard, and your own guide on the runabouts.
You can fish day and night.
I have been to the Sir Edward Pellew group of islands out of the McArthur river.
We stayed on one of the islands, fishing was just OK, accommodation was a a bit spartan, food was great.
We got GTs, Queenfish, Spanish Mackeral, coral trout, sweetlip, cod, Moses perch, red emperor, etc,
Great range, but not so in numbers.
