The National Broadband Network Company is leading the new infrastructure project
Telstra and Optus will close down their infrastructure and transfer² customers to the national broadband network.

Telstra will make A$11bn ($11.6bn; £7.2bn) over decades.

Australia's big distances and rough terrain³（地形，地势） mean high costs and slow internet speeds for many.

Optus, owned by Singapore Telecommunications, will make A$800m.

The deals are part of the government's plans to roll out a A$36bn national broadband network.

The project is led by the state-owned National Broadband Network Company.

The plan is to connect more than 90% of Australia's population to a fibre optic（光纤） network that will be among the fastest in the world.
