If you go to most beaches in Australia, you are likely to see women topless and many in G strings. Why not see that before you come to make sure you can handle it- so its not such a huge shock to see the naked body- We dont want you guys having heart attacks when you come here because your morals will be so offended.
Also I go on the bus all the time and hold my girlfriends hand or put my arm around her- Maybe the best time to see something like that is before you come here- I mean- noone here even batts an eyelid at us, but if you have just arrived from Saudi- You may get such a shock you will be outraged- and that would not be fair if you came here and want to live by our societies rules.
