Look for websites for Telstra and Vodaphone for a start. Also look for the Australian Broadcasting Corporation, Amalgamated Wireless Australasia and the Capital, Prime, Special Broadcasting Service and Win television networks.

Australia has been putting in a lot of optical cable over the past 15 or so years and there is supposed to be a complete switch to digital television soon. (Might not happen as quickly as it is supposed to - market resistance is high as the analog system -PAL-D - always gave a better service than the long obsolete NTSC.)
