If a network is covered then it is regulated and must have an approved access arrangement in place that sets out the undertakings made by the network, including terms, conditions, and price that apply to third parties seeking to use the network.
Under section 3.5 of the Code, the Minister must approve a coverage application if the following criteria are met:
- access to covered services on the network would promote a material increase in competition in at least one market other than the market for the covered services provided by the network;
- it would be uneconomic to develop another network to provide the covered services; and
- access to the covered services would not be contrary to the public interest.
The Code also requires the Minister to have regard to the geographical location of the network and the extent (if any) to which the network is interconnected with other networks.
The Code determines the process that the Minister must follow in assessing a coverage application. It establishes stages for public consultation and timeframes for decision-making by the Minister.
