Hey mate,
Try Julienne around at Little bay or South Maroubra. Plenty of fish there, Kings, Bonito, Mac Tuna etc. Spinning and softplastics. Yellowrock ( the furthest northern point of Malabar is good fishing too but very dangerous, not to mention the Great White that lurk off there too!
As far as bottom bashing goes i'm not sure where is a good spot. On a sunny day at malabar when the water is clear you can see the sandy patches so thats a good place to cast into. Even grab a snorkel and have an even better look.
Cheers and hope this helps.
