If your flying in the bush landing on ALA's/ remote strips etc always take some spares with you. Spare spark plug or two, and socket set to change, Landing light ,duct tape, zip ties etc. Water for you, couple of litres of oil, Know how to hand start your engine and carry out minor repairs. It is a long way for help to arrive. Never leave the aircraft unattended if cattle are near bye or Camels if overnighting unless you can barricade it away safely. They love using it to scratch on and can easily destroy the flying surfaces.
As above get reliable info on strip condition and fuel availability. Get reacquainted with direct reckoning / WAC charts for navigating as a back up. Watch the weather constantly. Dirt strips can turn into a quagmire quickly with a heavy downpour out bush.
