Ouyen is a small town in north-west Victoria. Home to a little over 1000 people. The bottom stamp is a Christmas Island Christmas stamp from last year. The other two stamps are also 2017 Christmas stamps which at first did't look all that special. But the images on the stamps are photos taken during the annual "Lights of Christmas" event at St Mary's Cathedral in Sydney, where lights and images are projected onto the face of the Cathedral during the month of December.
