Haven't read any previous posts, but to the OP, I would hold off watering for now: the rains are coming. Wet season is just around the corner. Once you start getting the summer rains and growing season, then your grass will come back good as gold. Fertilise, then keep up the watering once it gets to sort of March/April, one or two good soakings once a week.
I hate watering because it feels wasteful, but I get really disappointed in my brown lawn by November. I'll probably try grey water from my washing machine in a bit more earnest next year.
