Got an email from DeviantArt this morning:
Come to Austin, TX and hang out at our devMEET! OR just buy the t-shirt.
According to Expedia, a flight on United with one stop from Sydney to Austin is $1,636. That's a pretty expensive meetup and/or shirt ;)
Curiously, the cheapest flight from Singapore to Austin is on All Nippon Airways, probably goes via Narita.
