Hi! We are headed to Cairns in Sept and I am trying not to pay full price for a liveaboard to cod hole/coral reef, 4 or 5 night liveaboard, does anyone know how to get discounts on these kinds of trips? I am looking at Spirit of freedom, supersport-mike ball, taka and nimrod. Also if anyone has advice on which liveaboard they like the best, that would be great, thanks!
