Analysis: As fierce competition ensues in 50Mbps.

Aussie Broadband and Telstra have both upgraded the “typical” speeds that NBN100 fixed-line users can expect to see in the evening peak, breaking 80Mbps for the first time.

In the space of less than two months, Aussie Broadband went from 78Mbps to 84Mbps, while Telstra raised its numbers significantly from 60Mbps to 80Mbps.

That means the approximately 18Mbps gap between the expected peak performance of NBN100 plans that iTnews reported in January is largely maintained.

At the NBN50 tier – which NBN Co is trying to set as the most popular plan for all users – competition is fierce.

There is only 4Mbps of reported difference when it comes to the various retail service providers.
