Australia's two biggest telecoms companies have joined the government's A$36bn (£24bn) plan to roll-out high-speed internet across the country.
Telstra and Optus will close down their infrastructure and transfer customers to the state-owned National Broadband Network Company (NBNC).
About 60% of households have broadband, but speeds are slow compared with many industrialised countries.
The plan is to connect more than 90% of households to a super-fast network.
