The federal anti-corruption watchdog’s in-tray is filling up, with more than 300 referrals made to it since launching last weekend.

National Anti-Corruption Commissioner Paul Brereton said in his first speech on Monday there had been 44 referrals received via the body’s online system.

The commission updated its figures on Wednesday, revealing there had now been 186 reports submitted online and 116 phone calls.

About 60 of the referrals related to “matters well publicised in the media”, the commission said.

Mr Brereton warned on Monday against attempts to weaponise the watchdog through inappropriate referrals, adding he would not hesitate to make public statements calling out the unfounded claims.

The commission is tasked with stamping out corrupt conduct involving Commonwealth officials, including ministers, parliamentarians and their staff.

It will also investigate the conduct of public servants and government contractors.

Anyone can refer a matter to the commission, which will then decide whether to investigate.

The commission can also make its own determinations about what to investigate without a referral.
