"It only took one discussion and one appointment for the connection to take place. The connection went ahead quite quickly after that and it was on the 8th of December that the connection actually took place," she said.

The Point Piper house was connected on December 8, 13 days after NBN Co said it would pause connections to the HFC cable because of complaints over slow speeds, sparking a delay of up to nine months for new customers. HFC cables are those installed in the past for cable television services.

Opposition communications spokeswoman Michelle Rowland asked Mr Turnbull why he enjoyed super-fast internet at his mansion "when three quarters of premises on his copper NBN cannot get that speed?"

"Why is it always one rule for this born to rule Prime Minister and another for Australians," she said.

Opposition Leader Bill Shorten said Mr Turnbull's connection made his home the "envy of the rest of Australia".

But the Prime Minister said the government was connecting more homes at a faster pace and cheaper cost to the NBN than under Labor's original plan, which emphasised fibre to the premises connections.

"We know what the Leader of the Opposition is trying to do. He is trying to run his politics of envy, he is class war oriented," Mr Turnbull said.


Mr Turnbull said he was one of 411,000 customers using the NBN's "premium service", which in his eastern Sydney seat relied on HFC cables.

"This is the one the Labor Party said was second rate and outdated and should be dropped. That is what they said. They can't have it both ways," he said.

Mr Fletcher, who represents Communications Minister Mitch Fifield in the lower house, told Sky News the order for Mr Turnbull's connection had been placed before NBNCo announced its freeze.

The debate over the PM's internet connection coincides with the release of new figures by the Bureau of Communications and Arts Research claiming just 2 per cent of households will require faster speeds than 49Mbps by 2026.

Senator Fifield said the Coalition's NBN rollout would ensure 90 per cent of the NBN fixed-line footprint would deliver download speeds above 50Mbps, and all premises would be able to receive peak wholesale speeds of at least 25Mbps by 2020.
