Today, about 60% of West Australians will vote, in addition to those that have already voted and quite a few who won't. While the election will cost approx $20m to run, if the AEC enforces fines on the estimated 150,000-200,000 people who don't vote, this will reduce their net costs by a cool fe million dollars. At the midpoint, if the fine were to be increased from $20 to $120, then this entire election could be run at no net cost to the Australian budget bottom line.
If you would like me to run a scenario based on your estimated primaries, leave a comment below and I'll respond when I can. I will likely be busy from AEST 9:30am-1:00pm, and 5:00-7:00pm so there'll be chunks of today that I can't run my Monte Carlo model. I'll do my best though.
