If you get away with paying just the top tax bracket you are doing ok.

 Be doing well. I'm up there every year , starting soon, and it just gets worse every year. Some formerly productive spots are just now no-go zones.  You will have days where you don't get anything to the boat, other days will be better.  Big bull sharks are a real problem in the last 3 years or so, bloody fearless, have started taking sailfish, even. We don't anchor up much any more, which was what we mostly did. We only do it now when it is simply too windy to do anything else. Spend more time out wide trolling for billfish, where they don't bother us. But, go and deep drop on the same depths, and they'll clean you up. A bloke who camps just us from us every year, and only deep drops, has days where he loses everything. Then, he'll try next week, and not lose any, although those days are pretty rare, according to him.

it wouldn't be so annoying if they just left you a head, but they tend to go back for the rest, and get hooked up.  After saying all that, we still manage to get more than a feed, just make sure you use cheap lures if you are trolling for mackerel   I spend all year buying up my favourite lures when they are on special, grab a bargain when you see it.Doesn't hurt so much when you have only paid $12, instead of the normal retail $20.

the 60's and only managed to boat 1 or 2 demersals a day all the rest gone to sharks, it really pissed us off so we went out to 110m line and got a few small blacks, sailies and wahoo on the marlin pushers, as above use cheapest tackle you can get away with and keep moving if demersal fishing. I really think a cull is necessary as many fisho's like myself will not be returning to coral bay again and the few businesses in coral bay may start feeling it financially

Makes a interesting point about how the buggers learn to feed. ( those colour boards almost could be a boat hull)

And it questions to me whether there is a huge explosion of shark numbers around the reef or if thru learned behaviours 

us boaties are helping to train and consentrate those that are there.

Hence what we found up there recently, that on some days at some depths or spots ,we fished for a hour , boated say 6 or 8 fish , and never saw a shark.

The next day at a different spot in same depth we got hit straight away.

Theres no denigning there is a very very healthy shark population at ningaloo, but we caught some great fish , brought back plenty of fillets ,

had some great sunny winter weather , and enjoyed snorkling , swimming , and odd drink or too , so I would deff go back.

 was up there in may and the sharks were bad, but we still managed to get lots of fish to the boat. just need to keep moving around and dont stay on one spot to long.

 There is no question in my mind that they can learn, and learn they have. The very sound of an outboard, probably slowing, is enough to get them to come in. Forget burley, you just need a motor, and quite likely, the repetitive noise of a sonar. Down home, they learnt to follow crayboats. A charter operator tried to cash in on it, but found they simply wouldn't come around. He had a twin diesel setup, with surface drives, and, if he went close to a crayboat, they would briefly investigate him, then bugger off and continue to follow the old bait. 

We started seeing ths way back in the late eighties when we first fished Ningaloo--there were always sharks, but only an average problem--it is the tropics, after all. but, if you went back to the same spot 3 days in a row, they were waiting for you,even way back then. It was a lot easier to move around then, as you weren't hemmed in by the Sanctuary zones--I blame them for a lot of it, half the ground we used to fish is gone, so the sharks are more concentrated. 

Someone i knew related something that happend to them up there  a few years ago. they were fishing out in the deep, and one of the blokes hooked what he thought was a shark, unstoppbale, and he ended up cutting it off. They steamed off , he reckoned, about 2 miles, and dropped over again, and not long after, another shark hook-ip. This time it was on heavier gear, and they got it to the boat. And found the recently lost rig and a lot of line attached to him. They reckon he must have followed them flat -out to make it in the time elapsed.
