The Manus Island debates led me to notice I have travelled in far more dangerous places such as the Philippines. Also, if you are thinking are going to Bali, read its travel advisory.
When travelling to the Philippines, we make sure we are already outside of Manila because of the stray bullets on New Year’s Eve. There are guns everywhere. A M-16 looks a lot smaller in the flesh than on the telly.
Philippine banks have 3 security guards at the front with guns pointing horizontally ready to go at bank robbers. The Manila airport chief was assassinated a few years ago because she crackdown on corruption. The assassination was by a sniper.
Everything from airports to discos in the Philippines have gun deposit booths so that you and your bodyguards can deposit your guns at the door and collected them on the way out.
In Leyte, where we holiday at Christmas with family, it is common for politicians to have private armies of several dozen. When I was in the Philippines for a presidential election, there is a murder every day often of a rival candidate
My point is that the PNG is not the only dangerous country in Asia. If the asylum seekers from Afghanistan, and some are, the travel advisory is you are not safe even if you bring your own bodyguards.
About 200 of the residents of that camp have been denied asylums because their claims were not deemed to have merit. I do not see why Australia has any responsibility for them now. They are free to travel anywhere in PNG and anywhere else that will give them a visa.
