I came across this site while looking at cemeteries, it is for NSW and other parts of Australia and may interest anyone has not yet seen it. There is a photo of  John Augustus Emile Harris, he claimed to be 18 when he enrolled, he died  at Galipolli 8th Aug 1915, his age -15 years and 10 months. I don't think anyone would have mistaken him for an 18 year old.   www.gravesecrets.net/wwi-pictorial-honour-rolls.html
