Well we already have this to contend with:

Now, forcing tax collection from overseas retailers is actually not legal as they are not an Australian business with an ABN. That is the first, and in this case the actual last step.
Plus Foreign business does not lodge returns and do BAS. How are they to claim gst credits for gst collected? They can't as they don't even pay gst themselves in their own countries, and if they do, their country and ours are hardly going to be transferring gst credits with each other. How are they even going to submit gst collected when they don't even do an Australian return? Hell, do they even do 75000$ in turnover to begin with?
Being non residents for tax purposes, they owe us no tax at all anyway.
This is why they need to be collecting the tax upon importation and can't fob it to the retailer.
