Legislation for a national anti-corruption commission could be introduced to the federal parliament as early as next month.
Attorney-General Mark Dreyfus said he hoped the bill to establish the federal integrity body could be brought forward in the next sitting fortnight, due to take place during the first two weeks of September.
The establishment of the body was a key election promise for the new Labor government, which pledged to introduce legislation by the end of the year.
Mr Dreyfus said while such an agency would be difficult to establish, it was important to set up a federal body.
"It's going to be very broad-based, it's going to have full powers to conduct both private and public hearings, it's going to have full powers to report, it's going to be able to look at the whole of the Australian public sector," he told ABC radio on Friday.
"I'm hoping to be able to say we've learned from each of the eight state and territory commissions, and we're going to be able to pick the best features."
However, Mr Dreyfus said there were limitations in Victoria's Independent Broad-based Anti-corruption Commission which would not be included in the federal model.
The attorney-general said the federal model would have a broad focus and not just be examining federal MPs.
"This anti-corruption commission is going to make reports, and from reports, we'll get public exposure of corruption. From that public exposure, we'll get action," he said.
"This national anti-corruption commission is about eliminating corruption in public life in all its forms. It's to concentrate not just on MPs, but on ministers, on senior public servants, on every agency of the commonwealth."
The attorney-general hit out at suggestions from independent MP Kylea Tink, who has previously suggested a federal integrity body should have the power to sack parliamentarians.
"The power to sack parliamentarians rests with voters at the election," Mr Dreyfus said.
"Kylea Tink would probably now regret making this suggestion, which has been something of a diversion from what this national anti-corruption commission is going to be about."
The previous Coalition government had pledged to introduce a federal integrity commission during the last term, but the bill was never brought before the parliament.
An independent bill was proposed, with Liberal MP Bridget Archer crossing the floor to bring debate on the bill, but the vote was lost on a technicality.
