What were the living and fighting conditions for Australian soldiers in Papua New Guinea?

My Father never spoke of the war except to say that in Papua New Guinea he lived in muddy trenches. His feet were always wet and sore as it was always pouring rain. Leeches clinging onto their bodies were a problem all the time. Also said he lived on bully beef. As for the fighting, it was unspeakable except for the snipers he spoke of, the horrible living conditions and that it was a case of shoot or be shot. Not much help I guess for what you are looking for.
