Foreign Sellers

I'm an Australian seller trying to make a few dollars after expensive national postage fees, my question is why are foreign sellers (example China Hong Kong sellers with very cheap shipping fees) listings are placed before local sellers in there own country where foreign sellers products are up to half the price.

I find this is wrong & I hope eBay Australia will see this & start supporting local economys first before foreign sellers, national local sellers listings should be first, not foreign listings.
