There seems to be some rubbery figures doing the rounds with regards to converting between AUD$ & GBP in this discussion.
As per
OzForex.com, here are the going conversions:
24,050.00 British Pound = $61,476.61 Australian Dollar
7,500.00 British Pound = $19,171.50 Australian Dollar
[based on 1 GBP = 2.5562 AUD OR 1 AUD = 0.3912 GBP]
However, I readily agree that this is certainly not as much as it seems; I dare say that the crew won't living the high life on that sort of money in a town where the local cost of living is essentially GBP 1 = AUD 1 for most basic items.
