I feel your pain. In Darwin, historically demographically, there has always been more Men than Women (which goes against the National Demographic), most likely due to Male focused industries such as the Armed Forces and Mining.
Go to a Pub / Club on a busy night between Thursday - Sunday, and the ratio would be Men 55%, Women 45%.
However, it got way WORSE when the American Marines began to be stationed in Darwin. When they were on leave, and hit the town, they would flood the local main street of Darwin where the Bars are, and it would turn into a horrendous C!ck-Fest. I saw my favourite bar turn into 90% men, and10% women. I HATED it, when they were in town. I found them weird in a queer sense also, as they would all dance together.
As an aside, has the American Marines reduced or eliminated any physical restrictions upon enlistment? A vast majority of them I designate as Triple M's... Mexican Midget Marines. Most of them are tiny, and I'm not hugely tall, I'm 5'11". After a few drinks, I've been tempted to drop a smart-arse Star Wars quote to them: "Aren't you a little short for a Stormtrooper"?
