If you are going at high tide I would try the Bins at Cambois, just follow the road until you come to the railway and turn right. The road is not too good so take your time, park on the top of the bank before you go down towards Cambois pier and there is a good hole to cast into for a good two hours either side of high. Not sure about Cambois beach during the day, although you can get some decent flat's from there and also the odd Bass. Park in the car park opposite the Buccaneer pub and walk onto the beach I used to like about 200yards along to the right of the entrance to the beach. High water just try different casts both long and short to see what you can find, low water keep it close in as there are a lot of holes.
Just thought though, you might have quite a bit of fresh water coming down from the river which won't help a lot. You could try the bottom of the ramp though at the south end of the beach. When you cross the railway line towards the Bins, turn left and you will see the ramp down to the beach. Check the sea before you go though, if it is big you probably won't be able to fish the beach at all.
Best of luck wherever you try.
Jim.
