What is a portfolio?
A portfolio is a minister's area of responsibility as a member of Cabinet. As a general rule, there is one department in each portfolio.
The Governor-General appoints ministers, establishes departments of state and allocates responsibility among ministers through an Administrative Arrangements Order (AAO).
Each government department has its own departmental website with ministers and parliamentary secretaries often having their own websites as well. Within each portfolio there are also numerous agency and program websites.
