Hey Mel,

I had the same problem and it is not bugs. Even though we have had plenty of
rain in Perth it doesn't stop the annual draw down of soil moisture. In fact
the soil becomes water repelent and bypasses the grass roots.

I found this out after trying to dig a hole in the yard. 750mm down I had
something akin to hour glass sand. This was dry and wanting to cave in the
hole as I dug.

I have reticulation (bore) and moved a sprinkler to get better coverage on
the lawn. It has greened up a treat.

I hope this helps.

Cheers

Richard
