I am a huge proponent of outdoor education; I was a instructor for 3 years (bushwalking, kayaking, sailing, rock climbing, mountain biking) and now a teacher. I could go on and on about the benefits of outdoor education particularly to non academic students but also across the board. Most private schools in Australia see this benefit and have the money to run OE camps with a range of activities. I am also an advocate of public schooling and there unfortunately is not the money to run as many of these programs. It does not matter the activity the outcome is about team work, perseverance, and it also helps to get kids to cook for themselves for a few days. No need to bring guns in to it
I also agree military service should be a personal choice
