Earning GBP and spending AUD

[Fleeta]

guys, currently i've been socking away GBP on the basis that when I return to Oz in 2 years the AUD may have sunken a little. Anyone think this is a bad/good/indifferent idea. I'm hoping for AUD/GBP to be over 2 within a year or so, but I have no basis for that other than historical levels of where it has been. I'm assuming I should be hoping that Labour win the election for this medium term FX rate hope to come to fruition?
