Re: Can someone from Australia fill us in
Yes, the Australian Electoral Commission is a statutory agency of the Australian government (http://www.aec.gov.au/About_AEC/index.htm).
As well as conducting Australian elections, it conducts elections for other bodies like trade unions and I seem to recall it has also made some export sales of EasyCount. The EasyCount software at the heart of Michael Cordover's request is a money-making product for the AEC.
As others have observed here, it seems AUD 18m a year of revenue trumps the right to verify that elections are fair.
Sadly, public sector agencies in Australia often try to derive commercial value from their assets. There is considerable institutional resistance to open data. For example, the public sector mapping people have only just made geocoded address data freely available (https://blog.data.gov.au/news-media/blog/geocoded-national-address-data-be-made-openly-available); it used to be very expensive to get access to that data. Vital statistics registries have made profits from publishing birth, death and marriage data for family history researchers.
My understanding is that in the US there's a general culture of "the taxpayer has already paid for it, so the taxpayer should have it without further expense". That hasn't been the case in Australia.
While it's conceivable an incumbent government might attempt to tell the AEC to rig an election, it would be nigh-impossible to pull off. The AEC is an arms-length independent body. It determines electoral boundaries, and we don't have gerrymandering. If there is any flaw in EasyCount that allows an election to be miscounted or even rigged, I think it likely it would be by accident and not design.
