If we didn't do our work we would likely not be paid. So given we have little to show from our parliament over the past month in terms of productive work, we their employers wish all parliamentarians to pay back their last month's salary so it can be redirected into something more worthwhile such as a charity or climate change. 

There are 226 parliamentarians (150 from House of Reps and 76 from Senate) Their base pay is $200k per annun so this $45m per year cost to us translates to $3.75 million for a month.

Therefore we the people demand all these parliamentarians donate $3.75 million immediately
