Different councils have various by-laws governing all sorts of things.  Before installing a mast, you should consult your councils planning officer to ensure your installation will be legal.

In Victoria, there is a Telecommunications Facility Code Of Practice that sets the law for facilities in Victoria.  Councils often adopt these as the de-facto standard, but sometimes make subtle and important changes.  The thing you will probably be most interested in is if your council has altered the allowable height from the standard 5 metres.
