Jun's Neck Operation

I am raising money for my good friend and Zenbu Judo instructor Jun. Jun is really doing it tough at present trying to establish himself in Australia with his second baby due any day. Jun is a former international competitor and really loves to teach and compete in Judo however is struggling as he requires an operation. The type of operation in Australia is far too expensive and Jun has decided to go back to Korea to have the operation done for around $9K. If anyone can help him.. friends and Judo community I know Jun would really appreciate it. On top of this Jun is great guy and ambassador for the sport. Thank you.
