I thank Senator Birmingham for his contribution. I do not think I can be any clearer about what we did at the last election. This was our policy. We took it to the Australian people and they have re-elected this government. What we are now proceeding to do is implement the mandate that we received at the last election.

I think we are starting to go round and round in circles. At this point, I would like to table the supplementary explanatory memorandum relating to the government amendments to be moved to this bill. The memorandum was circulated in the chamber today.
