Never drop a passenger off in the middle of nowhere without ensuring someone is there to pick them up, people have died after being forgotten about.
Your passengers are likely to include indigenous Australians, learn how to deal with them and learn about them. In the event of a forced landing, an Aborigine who knows the bush is better than a survival kit. Show them a bit of respect and they will soon warm to you.
Take lots of photos, in 15 years time when you are in the cruise between London and Hong Kong, show them to your F/O.
