When a local told me that there was diving and snorkeling here, I thought they were having a laugh. It is a river after all, a busy shipping river with bad tides - how could that be good diving? Well it is true. Difficult to find details about online, google maps will not always get you there unless you know where you are going, but true. If you are diving without gear, there are a number of dive shops in the area, or even in Brisbane who dive at this spot. If you have the gear you want to head to Jack Evens Boat Harbour on Coral st. There is a little jetty people fish off and to the side of it you will see people going in to dive and snorkel. You can head along the wall toward the river opening and end up in a shallow sandy swimming beach, an easy area. If you are less confident, you can start in the large shallow lagoon. There is less to see in the lagoon but it would be good for building the confidence of an uncertain snorkeler. On the rocks you can see a very decent range of fish and if you are lucky, an octopus. Not a spectacular site, subtropical rather than amazing, but quite nice and very easy to access. If you want a regular swim there is the lagoon, if you want a lazy walk you can park and meander around the point out to Duranbah beach to watch surfers. It's a great spot.

If you know a local (like we did as tourists) and they offer to take you up the tweed river, then say yes! Beautiful! We had a lovely afternoon fishing and were spoiled with dolphins on our return trip to the boat ramp! Lovely adventure for everyone.
