I will tell you the exchange rate I am using 1 for 1.
It is NOT appropriate to use any exchange rate at all unless you are sending the money home.
A Ryanair pilot is paid in GBP and spends in GBP.
I liter of fuel in the UK is GBP1.30. in Oz its AU$1.30.
A Big Mac is GBP4.50 in Oz its AUD4.50.
Rent is several hundred pounds a week...in Oz it is several hundred dollars a week.
I spend quite a few days a mth in London and the costs in the UK are painful when you are not earning in GBP.
To suggest a Ryanair captain is making the equivalent of AU$245k is UTTER BS
There may well be a few unmarried Ozzies/Kiwis with no kids working at Ryanair who manage to save and repatriate some of their pay...that is the only part that is effected by exchange rates.
