Busking

I don't know about the other Australian cities, but in Melbourne in order to be allowed to perform on the streets people should buy the license for busking. The cost of the such pleasure is $20. For this price everyone get bill (which symbolize the license), booklet with information about basking and up to one hour presentation where is not allowed to play in the city and the other organisation questions.
I wonder how the Australian government treats this issue because, I'm not sure but, in Russia it's prohibited to perform on the street. I many times saw the police fines people who played musical instruments on the streets.
