Did you indeed fully complete sign up to Managed Payment before you sold everything?
Or maybe eBay is checking you are not drop shipping from China, as many of your ads look exactly like sellers who do do that but donโt state they do, just only putting โMelbourneโ as the item location
Are you in WA and the items in Melbourne? Since you post on the selling thread for Western Australia
There is a lot about your listings that would give eBay reason to take a closer look
