The Labor Party has called on the state government to explain why it needs a further $1.2 billion to meet new spending decisions after debate was gagged in Parliament for the third time this week.
Shadow Treasurer Ben Wyatt told WA Business News the state government is seeking a further $750 million on top of the automatic 3 per cent, or $437 million, Treasurer Troy Buswell receives from the previous year's appropriation under the financial management act.
He said while the Labor Party did not oppose the extra funds, it wanted to know details of how it would be spent with $200 million already expended at Mr Buswell's discretion.
"What we were trying to do was ascertaining where the money was being spent and how exactly it would be spent," Mr Wyatt said.
"In particular how much would be expended before the end of the financial year because that had an impact on whether the Treasurer actually needed the money now."
Mr Wyatt said he understood the funds would be spent on election commitments including $337 million for royalties for regions, health and a $150 million contigency plan.
He said the bill will now go to the Upper House for debate.
The state government has previously mentioned that it would seek a further $1.3 billion from the federal government for transport projects in Perth and Port Hedland.
