Either option is ridiculously overpriced for Australians. My flights to Denver cost $3000, a trip to Edinburgh would cost around $2500. That's not really plausible for me. I can't speak for any of the others (and I can't say what flying from NZ would be like) but as in most cases, we're paying around double. So unless one of us suddenly strikes it rich, I would not expect any of us to be able to attend, let alone donate to the running of the event.
