Mate not necessarily just for Yeppoon but near Cairns is the same sort of fishing, large reefies macks etc. I'd recommend any good quality spinning reel or overhead that can hold a couple hundred metres of 50-80lb braid. I use a Daiwa BG35 overhead with 80lb braid on it, rod is a Shimano, can't remember exactly which one sorry but didn't cost the earth, it also doubles as a nice trolling outfit. Other trolling rod (and spare bottombashing rod for emergencies only as the reel is heavy) is a TLD-25 with 65lb braid on a 24kg Ugly Stick. Lastly for throwing poppers etc I've got a supercheap Penn 950ssm on a Penn rod, came as a combo for under $200 from memory, that has 65lb braid on it too, just because I bought a big spool of 65lb. I know it isn't the best outfit and will fail me one day but it was cheap and is good for a few years while I convince my wife the benefits of buying a stella
Trace line around 100lb is a good place to start, some use heavier some use lighter. Only use good quality heavyduty swivels etc, they shouldn't be a lighter rating than the setup you're fishing, I match them to my trace line (i.e. 100lb). 8-12oz snapper leads are the go, make them up or you'll have to re-mortgage to afford a heap at the tackle shop.
For mack lures only bother buying Xrap 30s and Halco 190dd lures, as macks like both of them and use about 1-2' of 140lb single strand wire, not multi-strand and not straight mono as you'll lose some lures and macks don't mind hitting lures with the single strand on them.
Last trip I stayed at the big-4 park on the beach, lovely spot but kept everything locked up anyway, plenty of room to swing a cat or park a boat next to your accommodation. Cheers.
