Many stations get on the air for under $15,000 and can stay on the air for less than $1,000 per month. The main start-up expenses for a radio station are engineering fees, studio equipment for producing radio shows, and transmitting equipment for sending your signals out to the world.

It is better if you are in Australia when you apply for renewal as it is faster. If you have spent at least 2 out of last 5 years in Australia, your PR will be renewed online the same day. Otherwise, it takes 1-2 days. You don't have to apply before your PR expiration as long as you are in Australia. If you are planning to travel outside, apply at least a week before your planned travel just to be sure. #3
