In February 2025, former Finance Minister Simon Birmingham was appointed to lead the Australian Banking Association (ABA), the peak body representing Australia’s major banks. Having overseen financial regulation and economic policy as part of his ministerial responsibilities, Birmingham’s move into the industry he once helped regulate has stirred public debate about the ethical implications of such transitions.
His appointment is not unprecedented. Over the past decade, a number of senior Australian politicians have stepped into roles in industries they had formerly overseen. The trend is raising questions about conflicts of interest, post-political influence, and the safeguards currently in place to prevent undue advantage being gained from time in public office.
A Recurring Pattern
Several former ministers have moved into positions within private sector organisations connected to their former portfolios.
Christopher Pyne, after serving as Defence Minister, went on to join defence contractors and advisory boards. Ian Macfarlane, formerly Industry and Energy Minister, assumed leadership of the Queensland Resources Council and later took on board roles in the energy sector. Greg Combet, once Minister for Climate Change, has worked across roles related to energy transition, including as chair of the Net Zero Economy Agency.
While such appointments often cite the value of experience and policy insight, critics argue these transitions can create perceptions of impropriety—particularly if they occur within a short timeframe after leaving office.
The Ethical Dilemma
At the core of the debate is the concern that decisions made in public office might be influenced, consciously or otherwise, by future employment prospects. Even if no wrongdoing occurs, the appearance of a conflict can erode public confidence in government institutions and policy-making processes.
There is also the risk of former ministers using insider knowledge or networks in a way that gives their new employers an advantage over competitors. While lobbying restrictions exist, they do not necessarily prohibit advisory, executive, or board roles, which may allow for continued influence over policy from outside Parliament.
The situation is not unique to Australia. Globally, the so-called “revolving door” between government and industry is a well-documented phenomenon. Countries such as France, Canada, and the United Kingdom have implemented cooling-off periods of up to five years before former ministers can engage in related industry work.
Australia’s Regulatory Framework
Australia currently imposes an 18-month ban on lobbying for former ministers. However, this restriction only applies to direct lobbying activity and does not extend to broader forms of influence or employment within regulated industries. Critics have called for stronger, more comprehensive measures, such as extended cooling-off periods, clearer definitions of prohibited conduct, and greater transparency around post-political appointments.
Some have also advocated for the establishment of an independent watchdog to oversee ministerial conduct after leaving office, citing the need for consistent enforcement and public accountability.
The Other Side: Experience and Insight
Supporters of these appointments argue that former ministers bring invaluable insights to complex industries. Their understanding of regulation, policy, and government processes can help businesses navigate legislative environments and contribute positively to national policy debates.
Moreover, there is currently no legal barrier to such appointments provided lobbying rules are followed, and proponents maintain that post-political career opportunities should not be unduly restricted without compelling justification.
Nevertheless, the tension between public duty and private opportunity remains a delicate issue—especially when the transitions appear swift or poorly managed.
Public Trust and the Need for Reform
Public confidence in political institutions is already under pressure. According to recent surveys, politicians rank among the least trusted professions in Australia. The appearance of favouritism, whether real or perceived, risks further undermining that trust.
While the value of experienced leadership is clear, so too is the need for safeguards that ensure public service remains focused on public interest—not future opportunity.
The debate over post-ministerial appointments is ultimately a question of balance. Can Australia preserve the integrity of its political institutions while allowing former ministers to pursue careers in the private sector? Or is it time to consider stricter rules to separate governance from industry influence?
