Australian House of Representatives
The House of Representatives is the lower house of the bicameral Parliament of Australia, the upper house being the Senate. Its composition and powers are established in Chapter I of the Constitution of Australia.
The term of members of the House of Representatives is a maximum of three years from the date of the first sitting of the House, but on only one occasion since Federation has the maximum term been reached.
The House is almost always dissolved earlier, usually alone but sometimes in a double dissolution of both Houses. Elections for members of the House of Representatives are often held in conjunction with those for the Senate.
A member of the House may be referred to as a "Member of Parliament" ("MP" or "Member"), while a member of the Senate is usually referred to as a "Senator".
The government of the day and by extension the Prime Minister must achieve and maintain the confidence of this House in order to gain and remain in power.
