The majority of troops in the Second Australian Imperial Force ( the First had been formed during the First World War) were sent to the Middle East, where it was initially envisaged that they would train and then join the British Expeditionary Force in France. The 18th Brigade were on their way to the Middle East when France fell and were diverted to Britain where they formed part of the mobile reserve that was intended to meet the invasion.
