Thanks so much for your support guys. I really appreciate it. And you are right. It is not a nice feeling at ALL. I am sorry if it happened to you. :-(
As it turns out, my inbox was filled with shared files from the 'scammer' this morning. So, it seems that she has delivered. The order is almost complete.
It is definitely a good opportunity to learn more about the tell-tale signs of being scammed though. There is a great scam quiz on one of the ACCC or perhaps VIC state sites, which is helpful. And Scam Watch of course.
In this case, there were a few signs that it was a scam, but also her ABN on the invoice was legitimate - so that was one thing in our favour.
In the future, please note never to pay anyone you don't know by bank transfer - because if you need to dispute it the bank can't get the money back, and if they are pressuring you into making a payment or deposit quickly then that should be a warning sign too.
I hope you all have a good day.
Much love,
