Victorian Premier Daniel Andrews admits business case for failed Commonwealth Games was 'hardly the greatest piece of work ever done'

Victorian Premier Daniel Andrews has admitted the business case and costings of the cancelled 2026 Commonwealth Games was "hardly the greatest piece of work ever done".

Andrews also claimed he wasn't sure if individuals from the various organisations behind the business case for the event were currently working on any other major projects.

It comes days after the state government revealed taxpayers would pay $380 million in costs for the cancelled games.

Andrews today conceded the business case behind the event was flawed but said some factors were not "forseeable".

"It's the fact that those numbers were landed very late," he told reporters today.

"The decisions were made based on those numbers very soon after.

"It's hardly the greatest piece of work ever done, that's very clear.

"Some things are foreseeable and some things aren't."

The premier insisted he took "responsibility" for the abandoned games, saying he wasn't looking to shift blame.

"I'm not giving you the names of the people who did the work," he said.

"There's no need for me to do that because I'm accepting responsibility as the leader of the government for that.

"I'm not for a moment suggesting that people didn't do their best.

"I'm not for a moment suggesting that every single thing that affected these costs was foreseeable and ought to have been included. That would be unfair to say."

The opposition today questioned why the estimates weren't fact-checked much sooner.

"Why was due diligence not done? Why was that business case not properly tested?" Opposition Leader John Pesutto said.

"They must have known well before the announcement, that costs were blown out."

A parliamentary inquiry will soon commence into the axed games, with the results due by next year.
