Do Vietnamese in Australia know to "avoid" Chinese garlic contaminated with chemicals?

A Vietnamese woman in Inala, Brisbane was surprised when she discovered that the Garlic box that was advertised by the shop owner 'Australian Garlic for sale' was actually 'Product of China' garlic, some housewives in Melbourne would rather buy some Australian garlic is more than buying whole Chinese garlic packages. Is "cheap is worst?"
