After its return to Egypt, the regiment – along with the rest of the 1st Light Horse Brigade – became part of the ANZAC Mounted Division, and was given responsibility for the defence of the Suez Canal from raiding Senussi Arabs. On 4 August 1916, they fought in the Battle of Romani, before being withdrawn to rest and refit. The regiment rejoined the brigade in November and took part in the battles of Maghaba and Rafa in December 1916 and January 1917. This was followed by defeat in the Second Battle of Gaza in April 1917, and then the successful Battle of Beersheba and the Third Battle of Gaza in October and November.
