The Victorian Auditor General Office is conducting a review with the objective of assessing whether responsible agencies were effectively working together to reduce Victoria's bushfire risk.

Member for Polwarth Richard Riordan has met with officials to raise a number of key issues which he is pushing to be included in the review, particularly the inadequate replacement of power poles and a cost benefit analysis of the new Rapid Earth Fault Current Limiters system.

"These key issues should be included in the scope of report and about what is being done to prevent catastrophic bushfires such as St Patrick's Day, Black Saturday and Ash Wednesday," he said.

"Evidence is mounting that the primary cause of these catastrophic bushfires centres around aging infrastructure and very little is being done to rectify that situation," he said.

It was identified in the early 2000 that Victoria's electrical infrastructure was aging but little has been done to make sure the system is robust.

Powercor, which covers most of western Victoria, has a network of 571,800 power poles

Only four per cent of bushfires are caused by electricity infrastructure but they make up 80% of deaths because they happen on days of catastrophic risk.

But, in 2017 Powercor only put in 1153 new poles, a fraction of 1%.

Mr Riordan said Powercor knows it should be replacing 14,000 poles a year just to maintain standards, as he was told that figure by an official during a meeting.

A bushfire at The Sister was sparked after a rotten power pole snapped.

The Auditor-General Office overview said Victoria was one of the most bushfire prone areas in the world.

"This audit will examine whether responsible agencies are effectively and efficiently reducing the state's bushfire risks," it said.

"The increasing severity of weather conditions in Australia and across the world may lead to even greater bushfire risk in the future.

"While it is not possible to eliminate the threat of bushfires, the Victorian Government plays a key role in reducing the risk of bushfires and their impact on people, property and the environment.

"In 2013, the Bushfires Royal Commission Implementation Monitor concluded that the previous planned burning target of five per cent of public land to reduce bushfire risk was not achievable, affordable or sustainable.

"The Inspector General of Emergency Management agreed and recommended that the government replace the hectare-based target with a risk reduction target that measures the impact of fuel management activities on the overall risk of bushfires."
