The Queen has a big job. One of the jobs she has to do is sign the papers when new bills are passed. Bills travel through the House Of Representatives, where the members of the government debate it. After they debate, the government will vote yes or no for the bill.  Once they been voted fairly, it goes to the Senate. Then they will agree or disagree. When everyone agrees and the bill is passed, it will then go to the Queen and she will sign the papers. However, she is not always in the Senate to sign a bill so the Governor General, Sir Peter Cosgrove, sits in the chair, because she is very busy and cannot travel a lot to Canberra to sign the papers. The queen has sat in parliament only twice!
