While direct light is not good, the real problem is the illumination of the sky by the mass of lighting in the city. Just getting out of direct light doesn't solve that problem. Only km away can solve it.
Try here - Gembrook Sports Ground (50km - about an hour and nice drive). See here:-

Going there will also give you an idea of the sky problem. North, East and South are somewhat dark. West (in the direction of Melbourne) is all washed out and light. Same with South if you go to Romsey. Same with East from Bacchus Marsh. Same with North from MPAS.
Perhaps Johns Hill Reserve (26km - 40 mins - search Google maps)
