This accident happened in Australia, and as such Australian conventions for Last Light apply. Somewhat variable when compared to the UK since we have such a vast country and standard approximations just don't cut it. Before smart phones and apps there was a graph in the AIP which was used to calculate Last Light but these days most drivers either go to NAIPS or use apps such as OzRunways to get Last Light. The iPad in front of the UH-1 pilot would have undoubtedly had such a facility.
FWIW, NAIPS gives Last Light on the 6th September at Williamtown as 18:02 local, and sunset was 17:38 local.
