Melinda Cilento has been appointed a part time member of the Reserve Bank of Australia Monetary Policy Board, taking a seat on the body that sets the country's interest rates.
The appointment was announced on 14 August 2026 and runs for a five year term from 1 September 2026. Cilento replaces Professor Ian Harper AO, whose term concluded.
An economist with a policy institute background
Cilento served as Chief Executive of the Committee for Economic Development of Australia, the independent policy institute known as CEDA, and has been a Productivity Commissioner. Both roles sit in the space between academic economics and applied policy, which is the perspective the Monetary Policy Board is designed to draw on from its external members.
Her background is relevant to the particular composition question the board faces. Australia restructured its monetary policy governance following the 2023 review of the Reserve Bank, splitting the former single board into a Monetary Policy Board and a separate Governance Board. The intention was to strengthen the monetary policy body with members chosen specifically for expertise in economics and financial markets rather than for general business standing.
What the board decides
The Monetary Policy Board sets the cash rate, the instrument through which Australian monetary policy is transmitted to mortgage rates, business lending and the exchange rate. Its decisions are among the most directly felt of any economic policy body in the country, given the sensitivity of Australian household balance sheets to variable rate mortgage debt.
External members occupy a specific role in that structure. They are not central bank staff and do not carry operational responsibility, which is precisely the point: they bring outside judgement to the staff analysis and are expected to test it. A member drawn from a policy institute that has spent years working on productivity, workforce participation and the structural drivers of growth brings a supply side perspective to a body whose immediate decisions concern demand.
The productivity question
That perspective is timely. Australian policy debate has increasingly centred on weak productivity growth as the constraint on real income improvement, a question that sits outside monetary policy's direct remit but shapes the economy's capacity to grow without generating inflation. Cilento's work at CEDA and at the Productivity Commission has been squarely in that territory.
The five year term provides continuity across what is likely to be more than one interest rate cycle. Appointments to the board are made by the Treasurer, and this one was announced alongside the routine business of filling seats as terms expire.
Harper's departure closes a long association with Australian monetary policy governance, and the succession is a scheduled one rather than a mid term change.
