this whole thing is so stupid and petty, so really it's not surprising to see from our stupid petty government.
The funny thing is though, that even with 10% GST on top of overseas prices, Australian big box retailers that offer NO VALUE AT ALL over an overseas web page, like old mate harvey (whose corrupt lobbying is what got us here) is still stupidly overpriced and annoying to buy from compared to the overseas prices, and so even with GST, it's still worth shopping overseas anyway over going to harvey norman to buy something when time permits... so it's actually changed nothing - just slugging people a bit more money and effectively driving the cost of living up a bit more.
lately most of my imports are business expenses anyway - so once it kicks in, I assume every invoice for everything I import will be a GST invoice, and so I'll take that part back immediately, out of the GST that I collect.
