About Treasury

Treasury works to support the Government achieve its priorities and whole-of-government targets, while working collaboratively with all government agencies and consulting with the public on important policy issues.

Our Work 

Treasury is the central department managing Western Australia’s public sector finances and formulating and implementing the annual State Budget. We develop economic and revenue forecasts, and monitor developments in the State’s economy, major revenue bases and public sector finances, to ensure Western Australia remains on track against the State Government’s budgetary objectives and targets.

Our policy advisory role covers a wide range of issues, including Commonwealth-State financial relations, revenue policy, public sector wages policy, public sector superannuation policy, and advice on alternative models of service delivery and infrastructure provision. 


Economic assists the Government of the day through expert commercial, economic, financial and policy advice that promotes the public interest across a wide array of activities. This advice ranges from economic conditions, tax and royalty changes, the distribution of GST grants, best practice regulation, wages policy, and microeconomic reforms, to complex commercial transactions and projects such as the commercialisation of Landgate’s automated land title system. The team is a leader in economic and revenue forecasts and is responsible for modelling a range of economic policy options and settings to better inform decision‑making. Economic also promotes a whole‑of‑government perspective to negotiations of financial agreements with the Commonwealth and undertakes in‑depth analysis of important and emerging economic issues.
