To assist the decision making process.
You mention you would like to raise a family. Great you will probably want to live in a house. Assuming SYD, the average price is just north of 1 million.
A house at that price is probably 1.5 hour drive each way. Expect to do this 4-5 times a week, there is probably a podcast you could listen to that teaches Arabic.
You will start on FO pay so reduce those figures by 30%.
I’m guessing your lifestyle is better where you are. Just remember if you end up in SYD it will be tough.
In my opinion you need to be on $250K minimum to live comfortably in SYD anything less would be a ‘battle’.
If your arriving with about 3-4 million ready to settle down. Then relax, disregard all the above, enjoy the beers that will alleviate the frustrations of aviation over here.
Welcome.
