Dodo challenges TPG's unlimited NBN grip

ISP Dodo is the latest to weigh into the broadband market with an unlimited NBN plan, following TPG's lead in limiting it to the base 12/1 Mbps speed tier.

The M2-owned service provider today unveiled a vast range of plans on the NBN, including 'Lite' plans (with 10GB of quota), 'Big' plans (with 50GB), 'Mega' plans (200GB) and 'Ultra' plans for high-end users.

"Whilst the NBN is capable of delivering fast internet to the home, it is our job to make sure that it can be delivered to Australians at a cheap price," M2's consumer director Boris Rozenvasser said in a statement.

"It is with this in mind that we have launched what we believe to be some of the most aggressive plans in the market."

The 'Ultra' plans are likely to gain specific attention, owing to the $59.90 a month product which offers unlimited quota with 12/1 Mbps speeds. Opting for higher speed 'Ultra' plans — at 25/5, 50/20 or 100/40 Mbps — lowers the included quota to 2 Terabytes a month.

All the plans come with various commencement fees that bring costs for the first month to between $248.90 and $308.90.

Low-cost rival TPG offered a $69.99-a-month 12/1 Mbps unlimited NBN service last year. It included a phone service, but Dodo makes phone services an optional add-on.

TPG recently upped the ante by suggesting it would offer an unlimited NBN plan on the top 100/40 Mbps NBN speed tier by the end of this year. That will also come bundled with a phone service, at an aggressive $70 a month.

Small ISP AusBBS also offers unlimited NBN plans.

iiNet holds the lion's share of retail customer numbers on the national broadband network. About 30 percent of its 12,000 NBN fibre customers use a 12/1 Mbps product, according to figures released to financial analysts today.
