The Agreement was signed in October 2011 in Perth in the Commonwealth of Australia ( itself the third most populous Commonwealth realm , after Britain and Canada ) , which played host to the biennial Commonwealth Heads of Government Meeting ( " CHOGM " ) . Though taking place during the CHOGM summit , the Perth Agreement represents a side accord in Commonwealth affairs , since most Commonwealth member-states do not have a monarchical form of government - notwithstanding that Queen Elizabeth II is the Head of the Commonwealth
