So you want a level playing field Mr. Harvey?
Here is what you do: Sell on-line to over 200 countries, but don't charge them the Australian 10% GST. And it is legal.
You can sell to the European Union and save them 20% VAT. You can sell to New Zealand and save them 15% GST.
Boy, what a big kick start this will be for you.
But your prices will have to be competitive, as they buy from the same shop you do. It's called China. And your shipping costs will have to be competitive too, otherwise there will be no advantage for them to buy from you.
NOTE *** These comments apply only to what I consider low value goods. Under $1000AUD.
