Overview
A treasurer is the person responsible for running the treasury of an organization. The significant core functions of a corporate treasurer include cash and liquidity management, risk management, and corporate finance.
Government
The treasury of a country is the department responsible for the country's economy, finance and revenue. The treasurer is generally the head of the treasury, although, in some countries (such as the United Kingdom or the United States) the treasury reports to a Secretary of the Treasury or Chancellor of the Exchequer.
In Australia, the Treasurer is a senior minister and usually the second or third most important member of the government after the Prime Minister and Deputy Prime Minister. Each Australian state and self-governing territory also has its own treasurer.
