Mark,
I'd happily fish inside the Great Barrier Reef "lagoon" area and the top of Fraser Island with any popper in red head/white body, follwed by fusilier. The water is clear as air and typically less than 20m.
Down off Brisbane, where the locals (and myself pre-neck injury) were pulling our fish out of deeper water where dark blues/blacks/greens work on bright days and the 'panic trout' colour from FCL LABO works on overcast days. The water here is 15-30m and a lot darker too.
Regardless of where, contrast seems to be a key element across the board. Even the red head improves 50% by having a couple of black patches on the white belly........comes back to contrast!
Also, having a nice bright pink or yellow cup helps in tracking the lures movements:- both in the air and in the drink!
Cheers,
Aaron.
