Radio
Australia's national radio networks (Radio National, ABC NewsRadio, Triple J, ABC Classic and SBS Radio) have relay transmitters which allow each service to be broadcast as widely as possible. The ABC and SBS allow community-based relay transmitters to rebroadcast radio or television in areas which would otherwise have no service. Commercial radio broadcasters normally have relay transmitters only if local geography (such as mountains) prevents them from broadcasting to their entire market.
