But the government says it won't disclose the locations of the buildings, although it insists they pose "no immediate risk" and are safe to occupy.

It is also continuing to reject calls for an audit of privately owned buildings for flammable cladding, amid mounting pressure from across the property industry.

The government committed to inspecting territory owned buildings in the wake of the deadly Grenfell Tower fire in June 2017.

The audit quickly identified potentially dangerous cladding panels at Centenary Hospital and five other ACT health buildings.

But more than two years on, and with the audit still ongoing, few details about its wider findings have been made public.

Government figures provided this week to Greens crossbencher Caroline Le Couteur have shed some more light, revealing the audit has identified 70 buildings which might have potentially flammable cladding.

The Canberra Times asked building minister Gordon Ramsay for further information on the 70 or so buildings, including their location and the level of potential fire risk.

In an emailed statement, a government spokesman said it didn't intend to publish a list of the buildings.

The spokesman said none of the buildings were at "immediate risk and were safe to occupy". He stressed that the presence of cladding did not mean a building was unsafe.

While the ACT government has been inspecting its buildings for potentially flammable cladding, it hasn't subjected privately owned buildings to the same scrutiny.

Instead, it was relying on insurance companies to pass on information when the material was identified in a building.

The Insurance Council of Australia has cast doubt on that approach, saying that buildings owners, not insurance companies, were typically responsible for notifying government regulators about building defects.

Ms Le Couteur last month called on the government to take responsibility for auditing private buildings, a suggestion "fully supported" by the head of the territory's construction union.

A coalition of property industry and consumer groups has also been quietly lobbying Mr Ramsay to commit to a private building audit.

Master Builders Association of the ACT boss Michael Hopkins, Strata Community Association president Chris Miller, Owners Corporation head Gary Petherbridge and property lawyer Susan Proctor co-signed a letter to Mr Ramsay on August 22, requesting a meeting to discuss "increasing concerns" about combustible cladding in Canberra buildings.

Their main concern related to insurance for buildings where combustible cladding had been detected. In those cases, insurance premiums were "dramatically increasing" and owners were struggling to secure appropriate cover for their building, the letter said.

They said the ACT government should act quickly to audit "high-risk" buildings, as well as develop a plan for compensating owners and tenants.

The results of the audits should be provided to insurance companies and building owners, the letter read.

The groups said if insurers had flagged a building as unsafe, then "surely it was incumbent" on the government to rectify the problem, given that it was responsible for approving buildings for occupancy.

The Canberra Times understands a second letter was sent late last month, which included reference to measures other states have taken to address the problem in their jurisdictions.

The Victorian government has already pledged $600 million to rectify 500 high risk buildings identified in its own audit.

Mr Miller said the ACT should follow the example of governments interstate and develop a "plan of action that would bring some comfort to our market".

Insurance Council of Australia communications head Campbell Fuller said government-run cladding audits had helped owners "take appropriate action" when potentially combustible cladding was identified on their building.

Mr Fuller suggested the ACT government's approach was unusual, given that building owners - not insurers - typically informed regulators about building defects.

He was not aware of any insurance companies passing on information to the ACT government.

Owners and building managers are obliged to inform their insurance company if they become aware that their building is wrapped in non-complaint cladding.

Mr Fuller said while the insurance council had not seen a trend of higher premiums amid the so-called national cladding crisis, it was accepted that insurers could hike premiums - or refuse to provide cover at all - if a building had an "untreated ... amplified" fire risk.

Ms Le Couteur this week said there was an "urgent need" to inspect private buildings.

"The government has access to the expertise and funds needed to check private buildings quickly," she said.

"Relying on body corporates and commercial property owners to check their own buildings will lead to a patchy response, with potentially some unsafe buildings being left unchecked."

A spokesman for Mr Ramsay said the government's position on an audit of privately owned buildings "has not changed".

Government representatives discussed the ongoing cladding audit with Mr Hopkins and other industry representatives at a meeting on September 9, the spokesman said.

He said Mr Ramsay had committed to providing an update on the audit's findings by the end of the year.
