The possibility of flying out for this only became apparent to me very late on. I submitted an application as soon as I knew it was an option for me, which was the 22nd of April. Since it seems like applicants are already getting answers, I'm resigned to the possibility that my application was submitted too late to be considered.

Is that in fact the case? If so, it's probably worth modifying or removing the "Apply Now" links. If not though, I'll adjust my holiday plans accordingly.
