The Qld opposition leader says 1000 jobs have been lost at government-owned corporations over the past year.

Almost 1000 jobs have been lost in the past year from a number of businesses owned by the Queensland government, opposition leader Annastacia Palaszczuk says.

The Labor leader has been questioning the heads of government-owned corporations (GOCs) at budget estimates hearings.

She said on Thursday they’d confirmed 200 job losses at Energex, 199 at Ergon and 600 at Queensland Rail.

“It is so hard for us to get basic information, we have to ask the CEOs of the companies,” she said during a hearing with Treasurer Tim Nicholls.

“It’s like drawing water from a stone.

“I believe Queenslanders have a right to know.”

She asked Mr Nicholls to confirm the figures, which he did not do.

He said the information would be provided in each organisation’s annual report.

“I’m not aware of the number you’re after, because I don’t run those businesses,” Mr Nicholls said.

“It is something that is a variable and will change.”

The Newman government is planning to allow private investment in power distributors Energex, Ergon and Powerlink in exchange for a share of future profits.

The government says the deal, which would only occur after the 2015 election, would be worth an estimated $28 billion.

Energy Minister Mark McArdle says the job cuts aren’t to prime the assets for privatisation.

“Ergon and Energex are commercial entities that work independent of the government to get the best possible outcomes from themselves and consumers,” McArdle said.

“They have taken steps to introduce efficiencies and better outcomes for all concerned.”
