could it be that if there are domestic (non-GST) items intermingled with overseas/import (GST applicable) items that the system has a hissy fit? You have posted that it happens when there are cheap Chinese junk items in the cart. These would be GST applicable.
If you do have a mix of items then try this. Remove all overseas/import items and try checkout of ALL the domestic items. Then, having put all the overseas/import items on your watch list, put them back in your now empty cart then checkout ALL items again.
Not sure if this will work, but it would make sense that eBay have not got a handle of members having GST applicable and GST Free items in the one cart checkout.
