ISP iiNet has raised the bar on its "terabyte" broadband plans by extending the offer to new sign-ups on national broadband network (NBN) infrastructure.



The Perth ISP announced late today [PDF] that NBN customers on a 25 Mbps speed could opt for a terabyte of data quota from the start of next month.



The users would also get a free speed boost - from 25 Mbps to the full 100 Mbps down / 8 Mbps up "until June 2011", according to the ISP.



The temporary 100 Mbps boost applied not only to the terabyte plan but to all NBN fibre plans offered by iiNet. It was available to new customers.



"The main advantage of the NBN is speed," iiNet chief executive Michael Malone said.



"You don't know what it's like until you actually use a reliable 100 Mbps fibre connection in the home.



"You could download an album from iTunes in under 15 seconds, or grab a whole movie in a little under seven minutes, so we're also ramping up the amount of data included to make sure customers can really use it."



The Perth ISP was first to market with a terabyte of quota for DSL users earlier this week.



The move prompted competitors iPrimus and TPG to announce similarly high-quota plans (see comparison table here).

iiNet also unveiled increased quota on its other fibre plans for the NBN today.
