Eh....just check hers and your Life Insurance and Morgage Insurance policies . If Oz is anything like UK you will find that "dangerous sports" such as gliding, hang gliding. white water rafting and suchlike invalidates the policy. Wanna take the risk ?....have fun !!!....Incidentally "going for a quiet pint in Earls Court with Australian passport holders" is " a dangerous sport"...in my policies.........only kidding
