thanks everyone for your replay, i went to a different accountant and was told there is no GST on international sales as expected, but its strange that a different accountant would say otherwise, they might not know a thing or two on e-commerce. There is tax income but i was willing to pay it anyway as i have prepared my BAS and declared all income, its the GST that threw me off as i never charged it so paying GST would mean a huge hole in my pocket, glad it got sorted.
