If your in Perth and have sandy soils (like 99% of perth), I'd be doing more than just a turf underlay. I'd suggest adding clay (soil solver I found good, but there are others like sand remedy etc), and a good dose of either compost or you can get soil concentrates specifically for lawn from greenlife soil company. Anything to turn the grey shitty lifeless sand into something more of a loam that will support the lawn without the need for massive doses of fertiliser (that just mostly leaches away into the rivers anyway).
Result will be a lawn that uses way less water and is much much healthier. I did this to my rear lawn, and the difference to the front lawn which didn't receive anything special is staggering. Back lawn requires probably half the water, has no issues with weeds, pests or dry patches while the front lawn has taken me two years of work aerating, adding amendments and all manner of other works to get it to the same standard.
So you would suggest sandy loam underneath the grass instead of something like landscapers mix?
