Standard ADSL1 Broadband (all areas) ADSL1 is the most basic of the DSL broadband products available on the market. It is available at almost every exchange in Australia and has a maximum speed up to 1.5Mbit down and 256Kbit up. This requires a standard phone line to attach to and can't be used as a naked DSL service but can be bundled with a phone service in a package if required. You can change speed anytime to compare prices. *ADSL will be the maximum speed the line can handle. Some distance and infrastructure limitations may require a slower service.
