Sidelined minister John Sidoti has surrendered his ministerial salary and entitlements indefinitely, but not before earning as much as $17,300 in wages at the higher pay level while awaiting the findings of a corruption probe.

Mr Sidoti stood aside on full pay as Sports and Multiculturalism Minister on September 17 after the Independent Commission Against Corruption launched a preliminary investigation into his property investments.

But after coming under intense criticism for continuing to draw a full ministerial salary, worth $309,621 per year including entitlements, the Liberal MP for Drummoyne voluntarily gave up the extra money in November.

Government sources confirmed Mr Sidoti wrote to the clerk of the Legislative Assembly in November, requesting not to be paid his ministerial salary and expense allowance until further notice.
