The latest salary increase granted to the top bureaucrats in New South Wales has angered the State Opposition.

Under a Remuneration Tribunal determination that has just been posted on the Government Gazette, the salary of an executive office holder at the top level has risen by nearly $12,000.

The heads of the Premier's Department, Trade and Infrastructure NSW are now all being paid well in excess of $500,000.

The salary increases are in line with the Government's wages cap of 2.5 per cent for all public servants, but Labor's Walt Secord says it is too much.

"The Director-General of Premier and Cabinet now will earn $545,000. That's substantially more than the Premier," he said.

"Someone who's on a salary of $400,000 getting a 2.5 per cent increase - that is a hell of a lot of money."

Mr Secord says there is no comparison with the restrictions placed on the wages of nurses and teachers.

"A 2.5 per cent increase to a nurse or a teacher does not compare to a bureaucrat on $400,000 a year. You cannot compare them," he said.

"That is coming at a time when the State Government's cutting 5,000 public sector jobs and slashing $1.7 billion from education."

The Public Service Commission has been asked to review the structure of executive employment.
