Well I know 4 people in Albury-Wodonga (population 106,000) with machines. Current population of Australia is 22,680,000 so if Albury-Wodonga is the average (and in the unlikely event that I know everyone with a pinball in my town) then 22,680,000 divided by 106,000 and then multiplied by 4 (the number of known pinball owners in town) then there are 855.85 pinball collectors in the country. Problem officially solved!
