Cory's visit to Australia

Cory is our 14yr old son who has chronic renal failure, he has one dead kidney and the surviving kidney is only working at 24% but this is getting worse. His mom and I would like to take him to Australia to see his Aunty and Uncle. We want him to see as much of the world before he gets too sick. We would like to be able to take him around easter time so he can enjoy without being too hot. This would really help him as he doesn't get much vitamin D with our damp winters!

Thank you for any help in getting Cory on this dream trip. The money would pay for flights, accommodation and spending money for the three of us. Every little will help get us there 1000 people giving £6 WOULD get the target. Please help. His Dad Mark and Mum Chris.
Update:-
Cory has started a study to determine the affects of Kidney disease on the Heart, this means a few more tests when he attends his normal appointments but he wants to help others.

Update 2:-
I am planning to do a sponsored bike ride to work after Easter. It will be from home to West Bridgford looks like it will be over 20 miles and on a Brompton folding bike.  There are a couple of things to do first one is to get used to riding my bike again. I am also thinking of doing it in kit with armour and morian. Check back soon for more updates.
