The Kendell pilots that have gone to BE have either the right of abode in the UK or a UK passport. All are type rated and current CRJ pilots. The contract is for 6 months. What happens after that I do not know.
BTW, emigrating to Australia isn't as hard as it used to be. Check out <a href="http://www.immi.gov.au" target="_blank">here</a> for more info.
