What the operation of the Federation Chamber permits is for two streams of legislation to be debated at the same time. For example, at the time that a bill about higher education is being debated in the Federation Chamber, there can be a debate in the House about something to do with tax policy. Two separate bills are being debated at the same time. This means that the government can be progressing two bills over the course of a single day, whereas that may not have been possible in the past.
In our system, members have an opportunity to speak for 15 minutes in the second reading debate on a bill, so they're limited. I know that's not the case in some jurisdictions where they might be unlimited, but there is a limitation on the length of a member's speech in the second reading debate. If a lot of members wish to speak, then of course this will take hours. We have only 150 members, so it's a smaller chamber than yours; nevertheless, it's hours of debate.
It's not that the debate is going to be stopped because of the contentious nature of the legislation or the proposals, but it's just that if there were unhappiness about the bill being in the Federation Chamber at all, it is very easy to withdraw the quorum and then automatically the bill must be referred back to the House. I have to say this doesn't happen very often. It's usually because there has been quite careful negotiation between the leader of the House and the manager of opposition business to agree on the agenda for the Federation Chamber, so the bill will progress.
At the detail stage, if there are amendments being proposed by the opposition and they would like to record the formal division, then of course that must go back to the House. There are no divisions in the Federation Chamber.
