Currently, there is no constitutional system where there is a complete separation of powers. The strict doctrine exists only in a theory -- in reality, some overlap is inevitable, though a system of checks and balances has developed. In the Westminster system, ministers (executive) are required to sit in Parliament (legislative). This is to adhere with the concept of Responsible Government. This is also present in the Australian system, being a requirement of section 64 of the Constitution.

This is a list of active, dormant and extinct volcanoes in Australia and its island territories. Note that the term volcano is used loosely as it can include groups of related volcanoes and vents that erupted at similar times with lava of related origin. The lists provided below are mainly volcanoes of Cenozoic aged, with some notable older (Mesozoic and Paleozoic aged) volcanoes included. There are no volcanoes on the Australian mainland that have erupted since European settlement, but some volcanoes in Victoria, South Australia, and North Queensland were witnessed by Aboriginal people several thousand years ago. There are active volcanoes in the Heard and McDonald Islands.

For example, John Denver's ''Country Roads'' is a song with a bridge while Stevie Wonder's ''You Are the Sunshine of My Life'' is a song without one.
