Penny Arcade Expo is expanding to Australia, marking their first international event since starting up PAX in 2004. No date or event site was given, although Sydney seems like a prime location.

Penny Arcade’s Mike Krahulik and Jerry Holkins mentioned it in passing during a PAX Q&A session yesterday, adding that PAX Prime would be extended to four days next year.

It’s fairly certain that 2013 won’t see a PAX event in Australia (details would already be out), so 2014 is probably the sooner bet—and given how high attendance is for PAX Prime and PAX East, the turnout should be large.

No other regions were announced, although Krahulik did mention a desire to go to the United Kingdom.

PAX regularly attracts a rather large amount of attendees, with over 70,000 for PAX Prime and even more than that for PAX East—the event was so crowded, event coordinators didn’t bother trying to count heads.

By comparison, E3 pales with substantially less than 50,000 attendees in Los Angeles, the Tokyo Game Show averages 200,000; while Gamescom boasted a staggering 275,000 people this year alone.
