Have you thought of contacting the Dept of Veterans' Affairs If his grave is considered a War Grave, they might be able to supply you with a photo. I found a site (which I cannot remember) where you could could complete an application, send it to Canberra, a they would send a photo of the grave. I have obtained photos of a WW1 grave in France, and WW2 graves in New Quinea and Algeria. It look months however the photos 12" x 10" were worth the wait.
