some of them even have top rated seller status and have been selling on ebay for years

And an awful lot of them are not dropshipping as such, they have Aus bank accounts and register on the Au site but are really in China or HK and are selling direct on ebay as well as using naive sellers like yourself to dropship their cheap carp. You can see the same carp at markets and in cheapo shops, what you don't hear enough about are the raids that take place where the stallholders are arrested!

Over and over again people come here with tales of woe after dropshipping and finding out that eventually the proverbial has hit the fan.

At least as you are dropshipping you have not invested in thousands of dollars worth of stock, many poor saps have purchased a container load only to find it is worth less than nothing and can land them in jail after seeing their goods seized at the border and destroyed.
