I used to catch them during the night with bread, from my experience, must be some current, burley up with lots of bread, and you will hear the water boiling around the floating bread. Use the smallest float you got, 6-8 size hook, 10-20cm leader. When you put bread on the hook, make sure not to squish it, otherwise mullet will not bite, after cast out, let the current bring the bread to them, you will feel they are bitting, most of the time mullet will set hook by themselves. Mullet is great fun to catch, fantastic bait for big bream, Jew and Me.
cheer.
