Here's an interesting 'ready reckoner' for men to calculate their fortnightly pay if they enlisted in the A.I.F. Sadly, or pragmatically, it also listed the pension the family would receive if the man was totally incapacitated or Killed. At the time the average wage* for a man employed full time in a 'blue collar' type job was 60 shillings per week or 5 pounds, so this pay was about half the average wage, however they did get fed and clothed as the advertisement pointed out.
