Skimming through weather records of the Porth Arthur area, Aprils aren't all that hot (it's the middle of autumn so the traditional idea of a dog's day would be extremely rare), but considering that Richards is from Hobart, Port Arthur is a likely basis for the song (it could also be applied to any mass murder in general). The fact that the cafe where many of the shootings occured is called the "Broad Arrow Cafe" augments this.
Also I think the final line "let the world be kind to you" echoes "A Streetcar Named Desire", where one of the characters says "I have always depended on the kindness of strangers." She was raped, so the idea is that if you accept the kindness of strangers, you're going to have to accept their unkindness too.
