The Australian Greens want both major parties to urgently consider creating a national equivalent of the Independent Commission Against Corruption in light of recent scandals in NSW politics.
New South Wales state premier Barry O'Farrell resigned on Wednesday came after he gave misleading evidence to ICAC about a gift of a $A3000 bottle of wine.
No corruption accusations have been levelled against Mr O'Farrell.
"ICAC's value exposing the revolving door between big business and politics is evident to the nation and people are appalled that it is still going on," Greens leader Christine Milne said on Thursday.
"We need a national corruption commission because it's foolish to think this behaviour is isolated to NSW."
AAP reports a Greens bill for a national integrity commissioner is before federal parliament.
Among other measures, it proposes a new office of the independent parliamentary adviser to counsel members of parliament on entitlements claims and develop a legally binding code of conduct.
Greens senator Lee Rhiannon also called for a federal ban on corporate donations to political parties.
The Greens received the biggest single political donation in Australian history in 2011 when Wotif founder Graeme Wood gave the party $A1.6 million for a TV advertising campaign.
