My Dad emigrated to Australia when he was 17 - assisted by the Big Brother foundation who paid for his travel across the waves and arranged for his first job in the Bush.
When he turned 18 he was required - as were all Australian males at the time - to join the Australian Army under the National Service Act (1951). They were required to attend 99 days of full time training and then two years in the Australian Citizens Military Forces (rather like the Reserve forces or National Guard requirements of today).
My Dad has the best memories of this time - and he found me the below photo taken of him and some of his platoon. 2nd Lighthorse Division
Photo was taken at the Holsworthy Army Barracks - 1951.
Love you Dad :)
