Thanks too muss and cup-of-life. I have the cremation details on the death certificate, but good to see the death notice. The death cert has name "Arthur KELLS", the cremation and death notice "Arthur Henry KELLS", whilst the electoral roll (same address as on the death cert) has "Arthur Harold KELLS". I suspect it was Arthur Harold, as the informant obviously knew very little about Arthur.
I'm so sorry Sparrett! I must have been typing too quickly - the informant was Fred J EMPSON, "no relation, 70 Gilbert St, Dover Heights". I have an idea the house at Lilli Pilli was owned by Empson's son, but I can't remember where I read that, and can't find it now in my notes.
