I believe it's just essentially opposing the 50-day maximum writ period, which I would expect the government would be in support of, considering how well it worked for them in the last election. In fact, I remember being at Mercedes Stephenson's wedding when the election was called, and thinking, “Federal election—day one”. It was a sad day. It was a day in August.
That's just to say that you should support this amendment. This is something that has historically worked in the government's favour.
