Army Leisure Time
There was a big emphasis on leisure and organised sport on Rottnest Island during World War 2 and it's not hard to see why.
Personnel were isolated on the island, limited to their stationed posts and unable to wander around the island like a tourist.
Leave was not always a guarantee, particularly when the rough weather delayed the boat back to Freo for days or an alarm was triggered, warning of a potential enemy threat.
No one really knew if the Japanese would actually invade Australia but after the bombing of Darwin on 19 February 1942, the fear was surely a constant.
Working long hours or undertaking intensive training can take its toll on anyone, as we know ourselves in today's busy and time-poor lives. Although mental health certainly wouldn't have been something that could easily be discussed, quite like today, it certainly would've been an issue with all the emotions brought on by the World War 2 experience, as well as family separation.
Troops were rewarded with a regular swim in the ocean, organised games of tennis and cricket, movies playing in the settlement and even bands that came over from the mainland to play.
Keeping the ‘boys’ in good spirits was a main concern for the officers and commissioned staff. There was always a positive follow-on effect. It meant good team work, they were willing to work hard when required and performed their roles to the best of their ability, to name just a few.
