NSW govt spends $1.4b on consultants

The Public Service Association has criticised the NSW government for being "muppets" after a report that it has spent more than $1.4 billion on private consultants since 2011.

"The Liberals have made the state of New South Wales the biggest muppet in Australia," PSA general secretary Stewart Little said on Wednesday, accusing NSW Premier Gladys Berejiklian's government of being gullible while it "slashed and burned the public sector workforce".

Mr Little said the amount spent on private consultants contrasted sharply with the NSW Treasurer's decision to increase the "efficiency dividend" on public servants in last week's state budget.
