In February it was revealed the collapsed developer responsible for the project, Canberra's M and A Group, had been placed under administration owing more than $40 million.

The Indepent Property Group, which sold apartments inside the building, said investigations were still being carried out to determine the extent of defects within the 90 unit development.

Independent strata management boss Ken Nichols said they were also helping residents with advice on insurance.

"We are speaking with a number of parties for advice, this includes seeking legal advice on certain areas such as the builders statutory warranty," he said.

"Ongoing investigations are happening in regards to required defect works at the complex. At this stage there is no estimated cost as these investigations are still taking place."

A defects report obtained late last year showed the Esque building has been plagued with leaking toilets, faulty air conditioning and cracks in the walls and ceilings, among other defects.

Deloitte - appointed as the administrator of the M and A Group - said in February the company owed about $22 million in secured debts and about another $20 million to unsecured creditors.

A bad investment in Halcyon Rise Pty Ltd, a related entity involved in a failed Sydney property deal, was the main reason behind the collapse of the M and A Group, Deloitte said.

Documents filed with the Australian Securities and Investments Commission showed 97 unsecured creditors were owned an estimated $21,763, 694.

This included $113,000 for facade work on the development, $18,000 for shower screens and wardrobes, $38,000 for roofing, and $200,000 for electrical work.

The Gungahlin project had been plagued by a number of issues in 2017, including wrong colour schemes in some apartments and incorrectly sized whitegoods.

In June last year, residents were shocked when they were told to pay $563 for an electricity meter prior to moving into their units.

The developer changed tack a week later, offering to pay for the meters to compensate for the bungled colour schemes.

Deloitte administrator David Mansfield has said the matter was complex and investigations were ongoing.

"Our investigations to date indicate that funds to be recovered from the Esque units will not be sufficient to meet the outstanding secured debts, and as a result, a dividend return to unsecured creditors unfortunately appears unlikely," he said.

"We are in the process of convening a meeting of creditors, where we will be recommending that the company be placed in liquidation."

The M and A Group was approached for comment.
