My personal ABN Has GST Registered,
so I guess no matter what stuff I sell on eBay/Amazon,
I'll need to charge the GST to the customer, or consider the sale price has the GST included?
Even it's not working for parts stuff and only sell one item a month?
Cheers,
Are you selling them as part of your business or just a personal thing? If former, yes you'll need to charge and pay GST
