Mr Fraine has told the inquiry the department began exploring the QSAC option after it became clear that the Quirk review was going to recommend a new stadium.
"When the government understood this is where the panel was headed, it asked us to have a look,' he said.
"We knew the panel had had a look at QSAC and come to a view, we knew through the input of the IOC and Mr Coates, they had a view.
"They asked us to have a look … given the concerns the government had with a new $3.4bn stadium."
But pressed on what report was being relied on to agree to the QSAC option, Mr Fraine said the project validation report was now being completed.
"Aren’t we shooting first and asking questions later?" Mr Canavan asks, saying it seems the government is committing more than $1.4bn without any costings.
"That's the purpose of the final PVR," Mr Fraine says, adding it will be complete this year.
He is asked how much the report will cost – which he takes on notice.
