It is used for paving generally. The entire King St Wharf entertainment complex at Darling Harbour in Sydney and also two quadrangles at Homebush use Kota stone.

Child labour is illegal in India (where kota stone comes from) but no one ever goes to check that there are no children working there, or they are hidden from sight.
