Integrity will be back on the parliamentary agenda with independent MPs rallying to end the "jobs for mates" culture of federal politics.
Independent Sophie Scamps, who represents the Sydney seat of Mackellar, will introduce a proposal to legislate a transparent and independent process for major commonwealth public appointments.
The move will be backed by regional Victorian independent MP Helen Haines.
If passed, the legislation would create a public appointments commissioner and independent selection panels overseen by a parliamentary committee.
The new organisations would be responsible for major appointments such as the national anti-corruption commissioner and members of the Administrative Appeals Tribunal.
After a recruitment process, the relevant minister would be provided with a shortlist of three candidates to ensure the process is free from bias.
Dr Scamps said a decade of "cronyism and party-political appointments" had eroded Australian's trust in democracy.
"There is often more rigour and transparency for a $100,000 per year position in the public service, than there is for a government appointed $500,000 board position," she said.
"It is crucial the appointment process for important public positions is not only based on expertise but also transparent and free from undue political interference."
New polling by the Australia Institute shows 68 per cent of respondents think the government should be limited to appointing candidates who have been independently shortlisted.
Just 15 per cent said the government should be able to appoint whomever it liked.
