The regiment returned to the front on 7 June, relieving the 8th Light Horse Regiment on Walkers Ridge. The 2nd and 9th Squadrons manned the front trench, with the 6th Squadron in reserve. Trench warfare, shelling and sniping continued all month but there was no major attack. The regiment spent their time rotating through the front and resting at the rear. On 1 July reinforcements of four officers and ninety-seven other ranks arrived. On 18 July the regiment returned to the front, relieving the Canterbury Mounted Rifles, each squadron with two troops forward and the other two in reserve. They remained there until 31 July when they were relieved by the 10th Light Horse Regiment. Returning to the rear, the regiment only had twenty-four officers and 338 other ranks, almost 200 men short of full establishment.
