If it's a refund, why is it due? - Aussie Zone

Another bloody myGov scam

What a helpful, and totally not-dodgy site!

I followed the link, entered all my details and credit card number and everything! It turns out they already know all I need to tell them and I’m sure to see my refund in my account real soon!

tbh given how awful most government services are it’s not that surprising if someone gets caught by this
My god why do they not at least put in the slightest amount of effort to use HTTPS?
