Bribie Island

Try the boat ramp next to Silver Shores caravan park, about 500 metres before the bridge. Its well located for a paddle in either direction for whatever tide is running. My folks are staying there at the moment and dad rang me to brag about his 86cm flattie he caught today from shore at the mouth of the marina (next door). He also mentioned that a huge school of Longtail Tuna came into the passage very close to shore, some fish looked to be about a metre in length he estimated. Ive got to do a job up there on Friday morning, so I might take the kayak with me and get up there at day break myself.
Good luck.
