I transferred money from the UK last week for a home deposit in Aus. I got it at a reasonable rate and wanted to insure against further AUD appreciation which had been happening. I was worried about not having the deposit I needed for preapproval on a mortgage and to look for houses as I only have a small deposit which could make getting a good house tough if the aud appreciated much more. Now I'm stressed that I should have held out longer as the market reacted to poor china data and the pound appreciated.
I don't know how stressed other people get but I know the important thing is to know what you need in Aus and base a decision on that and not be greedy as you could get burnt. But I've never exchanged such big sums before and it's made me feel a bit sick! And I keep looking at the fx ticker frustrated.
