Our US correspondents, Chris and Charles have been covering the US voter fraud issue in detail. But the question arises about whether something like that could happen in Australia. It is doubtful that there could be the things here as seen in the US, allegedly, with the voting machines, and massive numbers of dead people voting for the Democrats, and open violation of electoral laws, but there are still problems with the Australian system, that a tremendous article, the best researched I could find, the Canberradeclarartion.org, has detailed. I was somewhat surprised to find that, as one politician put it: ““Electoral fraud, malpractice and errors are a common feature of the Australian electoral system.”
