I too face the same scenario, used to do some fishing in Sydney.
Just like the US, you will need a licence, yearly or daily.
To my knowledge after returning to INDIA, i dont feel there is any licence you need to acquire.
Though fishing in reserve forrests require forrest dept. permission.
The other thing to look out for is the local fisherman.
I live in chennai on East Cost Road, did some fishing or tried some beach fishing without success, was approached by many fisherman who live by the area and demanded that I leave, coz they feel if the trend catches on those guys will be out of business, eventhough we catch and release.
So the worst case you get finned from forrest Dept. or get manhandled by local fishermens......
