Next time you're pondering the various issues surrounding gender inequity, whether from a fiscal, sociopolitical, or possibly religious basis, take a moment to reflect upon where we came from, how far we've come, and how far we have yet to go in this area. I originally saw these rules on a colleague's notice board, and subsequently found a confirming source on the WicketyWicketyWeb.

There is no corresponding rules set for men. You'll notice the distinct lack of any rules pertaining to the actual teaching of children. The powers that were could have condensed this rule set markedly, by simply stating:

1. You are a woman, and a teacher, and therefore must not have any semblance of an actual life.

Australia during this period was by no means a shining example of cutting edge oppression, rather by this stage it was amongst the very first nations to have given women the right to vote (Women's Suffrage), so I imagine that cross-national similarities abound.
