Kingdom in June 1940 and the decision to adopt the British establishment of three infantry battalions to a brigade. The 19th Brigade was subsequently raised as the division's third infantry brigade, being formed by taking one battalion from each of the other three brigades when they were reduced from four to three. Of the division's infantry battalions, all except one – the 2/11th – were raised in either New South Wales or Victoria. In early 1940, the majority of the 6th Division was sent to Palestine, to complete their training before joining the British Expeditionary Force (BEF) in France. Together with the 7th Division they formed the Australian I Corps. However, France fell to German forces in July 1940, before I Corps arrived.

In September 1940, the Italian Tenth Army invaded Egypt, a British colony, threatening Allied control of the Middle East and most particularly, the Suez Canal and international supply routes. British forces under General Sir Archibald Wavell expelled the Italians from Sidi Barrani and pursued them back towards the Libyan border. In December 1940, the 6th Division was moved forward from training camps around Alexandria to relieve British troops around Bardia and at the end of December they were ordered to prepare to attack. On 3 January 1941, at Bardia, a small coastal town just inside the Libyan border, the first major Australian action of World War II took place. Amidst a heavy artillery barrage and supported by British Matilda tanks and Bren carriers of the divisional cavalry, the
