Businesses are ranked as in the fairly rated method, but only those whose name and website each appear in no more than two places in Australia are listed, so chains and franchises are left out. Each needs at least five Google reviews.
A business that shares its name with unrelated businesses elsewhere can be left out by mistake, and being part of a chain says nothing about quality.
