Under section 152AQB of the Trade Practices Act 1974, the ACCC is required to publish, by written determination, non-binding model terms and conditions of access for each of the 'core' services, defined as:
the domestic public switched telephone network (PSTN) originating and terminating access services
the unconditioned local loop service (ULLS)
the local carriage service (LCS)
any additional core service specified in regulations by the minister.
The ACCC may take into account any model terms and conditions when arbitrating access disputes.
In October 2003, following a public consultation process, the ACCC issued model price and non-price terms and conditions. In September 2008, the ACCC proposed changes to the model non-price terms and conditions.
