The tide times also differ depeding on how far up the river you acctually are. I know in the Brisbane River (Where I fish regularly) the tide table may say 'High at 7:30 p.m.' for the Brisbane Bar. But as i am much further inland and up stream then the Brisbane Bar I know to add approx. 40mins on top and that gives me a pretty much spot on time everytime.
For the Maroochy River I would take 1min off the Maloolabah tide time. Then add another 20-30mins depending on how far up stream you are. Or you could take your kayak to the Aussie Fishing Park which is on the Maroochy River at Bli Bli and troll around there in the Mixed Species pond I have caught many thumper Bream at that park. As long as you give them some notice that you will be bringing your yak there and you pay what you usually would to fish the park they don't mind.
