Looking for tips on getting my lawn (Sydney) back to something reasonable.
Basically, it looks like much with a scattered strands of grass up to 6"
long.

I guess it is a matter of what cutting and fertilising pattern to follow
i.e. do IO cut low to make it branch and run, or cut high frequently?

As I said, mulch, the lawn is surrounded by tree, but I should be able
to at least get a good patch back in the centre.

TIA
