Don't say we didn't warn you! Late last week we informed you that three day passes for PAX Australia were already 50% sold. Now they're 100% sold.
Individual day passes are still available at this point, as are BYOC (Bring Your Own Computer) passes. At this stage, however, PAX Australia has yet to release any information on what will be going on during individual days. That said, it's PAX, and if you plan on wandering around the booths and just exploring, I'd imagine any single day pass would suffice.
If you're looking and waiting for something more specific, however, it might be worth waiting until more details are released.
