@cove , I found it really odd, returning home. We were posted to the US, which we loved, and were given a lot of support and help to settle in and deal with the culture shock of moving there, which actually was a bit more than initially expected. When we first arrived, there was the obvious "honeymoon period", and we thought oh well, they speak English here and we are very familiar with American culture from the movies, TV show etc, how easy it will be! However, after about 6 months it really hit me just how different Aussies are from Americans in some ways, and how similar in others and I definitely felt culture shock and a bit homesick at that point. This soon wore off though and the time we spent there is a golden period of my life.
I certainly did not expect ito have culture shock though on return to Aus. However, we were not supported by the military at all with return - I suppose they thought we were just pleased to be home. It took a long time to settle back in. We were home, but had no real idea what had happened here whilst we were away (1990-1992 - so the pre-internet era which meant very limited news from home whuilst we were gone) and so we kept missing the "in jokes" and references to social occurrences and politics, suffered a bit of relevance deprivation syndrome after a couple of years of the high life and being regarded as something special/unusual in the USA, and of course we were not prepared for the total disinterest or even aggressive dismissal of our time away by many in our social circle. I honestly found the adjustment to being home harder than it was to the adjustment when we arrived in the USA. Mind you, it was awesome to be back near the family (well near in military terms anyway), and to be able to get back on with my "real life". I've since heard that this experience is very common for those of us lucky enough to be away and then return.
