For the next two and a half years the brigade saw service in the trenches along the Western Front in France and Flanders, taking part in actions at Bullecourt, Polygon Wood, Villers–Bretonneux and along the St Quentin Canal. Their final engagement came around Beaurevoir in late September and into early October 1918 when the Australians undertook operations to penetrate the German defences along the Hindenburg Line. During the brigade's final attacks, the brigade lost 32 officers and 489 men killed or wounded.
