Xcel are you referring to Australian jobs or PNG jobs?
Things may have changed in PNG since I left a decade ago - but I'd be a bit surprised if they have changed that much - in the 14 years I was there I don't know of anyone getting an initial job in PNG via snailmail. Email was yet to be invented. Subsequent jobs a different matter (you were a reasonably known quantity after 12 months) but initially meet and greet was about the only way - 98% of the time anyway.
