Parraman,
I'm thinking you are from parramatta??? if so why not fish for carps there?
During highschool (13 years ago!!!), we used to go to the bridge (near all the cafes and maccas) and use to have a ball catching them.
Also Penrith is good too.
As for baits, we used bread and also corns but later we developed a killer bait mixing bread, corn, flour, yeast to make a dough.
They great fun to catch if they are around. Great on light tackle.
If you're keen on freshwater fishing instead of just carping, go down to Penrith weir, best time would be 1hour before sunset, use worms for Bass (great fighter and good tasting according to my hungarian mate), bread for mullets and you know what to use for carps
