NBN Co will make a 25/5 Mbps service available on its fixed wireless network as early as June.
The network builder said in a blog post that the speed tier would also be offered on long-term satellite services when they launch in 2015.
Faster fixed wireless speeds had been mooted by NBN Co in product data sheets (pdf), but the company had never indicated when it would offer an advance on the basic 12/1 Mbps service.
"The wholesale prices for internet service providers who supply rural broadband users will be pegged at the same rate as they are for fibre users in the cities: $27 per month for the 25/5Mbps service and $24 for the 12/1Mbps service respectively," NBN Co said in a statement.
Communications Minister Stephen Conroy said the speed increase would give regional and remote internet users "significantly faster speeds than what is available now through ADSL".
"This upgrade represents a doubling of speeds for the NBN's fixed wireless and satellite services," Conroy said.
