Err which developed country pays a 777 Captain A$160 000? US176 000?
Easy Jet/RyanAir pay their 737 captains more than that!
Any airline in the USA would pay more for a 777 captain!!
While it's a alot of money in anyone's language Australian pilots do tend to be on the lower end of the scale.
However you do have to consider cost of living, Forex and tax in the equation which makes it an impossible thing to compare country to country
