In the Monetary repect your story above is similar to the states. Rates are paid living on the type of currency for the country. You cant compare AU Dollars to US or South African Rand. When in South Africa and flying the rates are pretty good in Rand, IF you are lving on the Rand etc......Dont expect to come to South Africa for Example and get rich enough to come to the States . The rate of exchange is about 7/1.
Other than that Fly what you need too and log what you have too.....ha ha
