Craig Foss' role as Minister of Veterans' Affairs has led to a hobby.
He travels the country attending "very good, apt and appropriate commemorations" at service cemeteries, then goes online to find Commonwealth War Graves in cemeteries nearby.
There are many reasons why soldiers don't always lie in dedicated cemeteries, such as the wish to be buried in a family plot.
The Commonwealth War Graves Commission ensures the 1.7 million people who died in the two world wars will never be forgotten. It cares for cemeteries and memorials at 23,000 locations in 154 countries, raising funds for standard headstones.
"Normally I would go to a service cemetery, where I would pay my respects there, and then I would look up the cemetery online," Mr Foss said.
