I move:

That the business of the Senate notice of motion proposing the disallowance of the Social Security (Administration) (Trial Area) Amendment Determination (No. 2) 2017, standing in the name of Senator Siewert, have precedence over all government business until determined.

I rise today briefly to inform the chamber that the opposition will be supporting this motion. Given that today is the last day that this matter can be dealt with in this place, it's important that we see this motion succeed to facilitate debate on the disallowance as a matter of priority.

Question agreed to.
