NSW 80 class in South Aust

["Peter & Sue Cokley" <petan@ion.com.au>]

   Hi folks

Some years ago  some NSW 80 class went to Port Pirie and [I think?] worked
on Leigh Creek coal hauls as well as through freights.

I am seeking any details such as;  how long did this go on for / loco
numbers / colour schemes / types of trains worked / reason for the NSW locos
working in South Aust / etc.

Thanks for your help
