The House of Representatives has been dissolved after a proclamation to do so was read by the Official Secretary to the Governor General.
Stephen Brady read the proclamation just before 5.30pm on Monday August 5 at the front entrance of Parliament House in Canberra.
The Clerk, Bernard Wright, Deputy Clerk David Elder and Serjeant-At-Arms Robyn McClelland were also at the ceremony.
The dissolution of the House has effectively ended the 43rd Parliament so that writs can be issued for the federal election on September 7.
A copy of the proclamation has been posted at the door of the House of Representatives chamber.
Dissolution of the House means that all business before it is now terminated and committees cease to exist.
Members cease to be members but ministers continue in office.
