Design
Sydney was a Town class light cruiser, of the Chatham subclass. She had a standard displacement of 5,400 tons. The cruiser was 456 feet 9.75 inches (139.2365 m) long overall and 430 feet (130 m) long between perpendiculars, with a mean of 49 feet 10 inches (15.19 m), and a draught of 19 feet 8 inches (5.99 m).
Coal- and oil-fuelled Yarrow boilers were connected to Parsons geared turbines, which provided 25,000 shaft horsepower to the ship's four propellers. Although designed with a maximum speed of 25 knots (46 km/h; 29 mph), Sydney achieved a mean maximum of 25.7 knots (47.6 km/h; 29.6 mph) during trials. Her economical cruising speed was rated at 11 knots (20 km/h; 13 mph) in 1921, and 11.5 knots (21.3 km/h; 13.2 mph) in 1926.
The standard ship's company was 376 strong, but during wartime, this would increase to the maximum of 475; 31 officers and 454 sailors.
