This reminds me that I was a little kid, I had heard of marriages being 'annulled' and I thought at first that meant that the police could just randomly turn up on people's doorsteps and tell them 'your marriage is null!' and turn one or both of the couple out of the house! I was scared at first that someone might suddenly come to our house and turf my parents out.

This story is just as childishly ridiculous in real life, and it's shocking that it could be allowed to happen.

BTW, the UK now has same-sex marriage; but Australia doesn't, so it may be Australia that's driving the nuttery (though trying to get any sort of bureaucratic mix-up sorted in the UK can be a bit surreal).
