@Justin241 , from a Sth Australian perspective I can see where you are coming from.
However - the guys who set up the protocols are not playing games, and they will be looking for someone to make an example of.
We've all seen those 2 obnoxious Brisbane girls who went to Melbourne, and they will be paying off their fines for a long time. There are lots of others who have been "made an example of" and if that happens to you and your guests you will get no sympathy from the public at large.
So - while it's not likely Qld will still be under these restrictions in October, I suggest you prepare your guests for an alternative (small) wedding option.
(Our own son got married a couple of months ago; with only 6 people allowed, none of either family could attend; just best man/maid of honour/celebrant/photographer).
