Laws to put in place a national corruption watchdog will be brought to federal parliament in two weeks.
It is understood the Labor caucus will be asked to approve the bill on September 13 before it is introduced to the lower house the next day or day after that.
The Morrison government had flagged the formation of a Commonwealth Integrity Commission, but did not bring its bill to parliament.
The National Anti-Corruption Commission (NACC), as Labor's model will be known, will have a broad jurisdiction to investigate Commonwealth ministers, public servants, statutory office holders, government agencies, parliamentarians, and personal staff of politicians.
It will be able to launch inquiries into serious and systemic corruption on its own initiative or in response to referrals, including from whistleblowers and complaints from the public.
The commission is expected to be overseen by a parliamentary committee.
