CSIRAC was the first computer in an Australian University and the first in Victoria. It provided a computing service to scientists, engineers and the Melbourne business community until 1964.

CSIRAC still exists intact and is on display at Museum Victoria: CSIRAC, making it the oldest surviving electronic computer in the world.

An excellent book about CSIRAC is Last Of The First, by Doug McCann and Peter Thorne. This book provides a comprehensive overview of CSIRAC, published by the University of Melbourne, and available free as a PDF (4.9 MB).
