It's very frustrating when this happens, and they only get a minor slap in the wrist relative to the potential (and let's face it, almost certain) spike in infections and financial costs that they will cause. This is why the declaration system is flawed when you just trust people to properly disclose information, because there will always be a group who don't care and lie. These very people are filming themselves deliberately antagonising and breaking the rules to post online to get views, it's so screwed.

And now you have the tourism group complaining about the border shutdown to people from Sydney, when the alternative is wait for it to inevitably cause a spike in infections in Qld and close the whole state again. Just when I felt it was almost back to normal this happens in my area...
