The LRRSA has a number of articles on the State Rivers and Water Supply Commision (SRWSC, S. R. & W. S. C.) tramways, starting from the late 1960's. I'd bet something would be in there.
Peter Charrett wrote a multi-part series of articles on the Tramways of the State Rivers & Water Supply Commission starting in Light Railways 21 (Spring 1967), but although Redcliffs was shown on the map in the first part, there was no mention throughout the series. In LR 28 (Winter 1969) Frank Stamford added some information to the article:
REDCLIFFS PUMPING STATION
There were three 2-ft. gauge locomotives here, including a Kerr Stuart 0-4-2T, B/No.742, built in 1901, and rebuilt by Kerr Stuart in 1903. It came to Redcliffs in 1924, having previously been used at Cobdogla in South Australia, and in Zeehan, Tasmania. The other two locomotives were Malcolm Moore tractors, one having an 80 h . p . Hercules diesel engine, the other having a Ford V8 petrol engine. The diesel was derelict in 1953, but the Ford engined job is retained for occasional use. The Kerr Stuart has been "preserved" at Redcliffs.
That appears to be the only reference (other than references to the loco in articles on Cobdogla or the RCHSR)
Here's another photo showing the inside of the boiler house, showing 2' gauge track and a turntable:[img]http://i164.photobucket.com/albums/u23/duttonbay/Odd%20Photos/20130518-174429_zpsdbe17d7c.jpg[/img]
