I often see job postings that allow remote workers, but only from Europe or North America.  This ignores a pool of talent that has advantages that you may not have thought of.  Australia is often seen as being in an "inconvenient" timezone, yet if you want to cover the "swing shift" between North America and Europe you need look no further than Australia.

When I get up in the morning it is in the US afternoon, when I leave work it is the European morning.  So I get to cover those times that others do not - or would be expensive to do so.  I have been doing this "swing shift" for 10 years now, and providing value for the companies I contract to.  Why don't you consider Australia for your next hire.  We even speak English!
