Al I have never had a fish jump into the boat fishing the GBR, most reef fish are bottom fish and its very hard work when they take your bait to keep them away from the reef and to wind them in as fast as you can before the sharks get them, do that all day and you will sleep well that night lol.
The thing also the GBR is the largest reef in the world, I have only fished it at the bottom end of the reef, Lady Eliot Island is the beginning of the reef just east of 1770 and travels all the way up to the top end of Queensland coast and top of Australia, well over 1k kms, but the further you go up north you get all the tourist ports of Townsville and all the day tripper cruises to the reef, it's a big money making business with charter boats galore.
Captain Cook who discovered the east coast of Australia had problems finding a way through the GBR and tore the bottom out of the Endeavor out from Cooktown, he had to beach the Endeavor for months and named the river after the Endeavour while they repaired the ship, also gave him time to climb the ranges and find a way to get out of the reef, even ships today has to have a reef pilot to navigate the whole inside of the reef and times they can get through the channels.
There are some of the biggest reef fish you can't eat because they are toxic from the reef food they eat, we also have some very deadly reef fish and things that want to eat you to be careful of, sharks (bull sharks are the worst ones), stonefish, even crocs have been sighted offshore, just to name a few but the colour of the reef as well the fish is such a draw card to our lovely part of the world and being in the tropics all draws the crowds and overseas visitors and the best thing, us Queenslanders are a friendly bunch.
I should get a job with Queensland tourism lol, but if you get the chance to come over our way, the reef be the high light of your stay and the beer is always cold.
