In Australia, the Treasury Portfolio refers to the eleven organisations that nominally fall under the auspices of the Australian Treasurer. The agencies undertake a range of activities aimed at achieving strong sustainable economic growth and the improved well-being of Australians. This entails the provision of policy advice to portfolio ministers whom seek to promote a sound macroeconomic environment; effective government spending and taxation arrangements; and well-functioning markets. It also entails the effective implementation and administration of policies that fall within the portfolio ministers' responsibilities.
