Over half of Australians will see the cost of their internet plans rise under NBN’s updated wholesale pricing proposal, with the majority of Telstra and Optus customers set to be hit with a hike.

NBN Co’s revamped pricing proposal, known as the Special Access Undertaking, was released last week.

Under this proposition, 50Mbps plans, which are by far the most popular in Australia, will see a base wholesale cost increase from $45 a month to $50 a month.

Meanwhile, the cost of 100Mbps plans and higher will fall from anywhere between $3 and $10 a month.

According to ACCC’s data, less than 10 per cent Telstra customers are on 100Mbps or higher plans, with only 14 per cent of Optus customers at this higher level.

More than 30 per cent of Aussie Broadband, TPG, and Superloop customers are on 100Mpbs plans or higher.

Despite this, Optus has welcomed the SAU, Telstra is yet to comment, and TPG has hit out at it.

“If NBN is truly committed to affordable broadband, then it should reduce prices for its most popular speed plan,” TPG external affairs boss James Rickards said.

Vocus, who owns brands iPrimus and Dodo, only has 14 per cent of its customers on 100Mpbs or higher. It also slammed the NBN’s pricing proposal.

“The SAU needs to make affordable broadband available through simple, low-cost, entry-level services; and provide choice for consumers by establishing ‘pull apart’ pricing to address a range of market needs,” a Vocus spokesman said.

“The SAU does not resolve the issue – rather, it will make it more operationally and financially complex for all RSPs to manage.”

NBN Co expects that more than 50 per cent of plans sold by 2030 with be 100Mbps or higher.

No doubt this pricing structure is designed to bump customers towards the better-value, more expensive, 100Mbps+ tiers.
