Military??
There is too much military influence in civil aviation, and one of these influences is drinking alcohol. A small ammount of alcohol can be beneficial, but too much is VERY harmful. Alcohol is one of Australia's most harmful drugs, and the Australian Government earns lots of money from the sale of alcohol. You could say the Australian government is involved in drug dealing, both alcohol and nicotine.
The military?? Well the military people often have to handle terrible situations, and do terrible things. They don't want their people thinking too much, so they use alcohol to keep their people "fat, dumb, and happy"
This is not appropriate in civil aviation.
