All Meet & Greets at VidCon are allocated via a lottery system. Every year VidCon hosts a Meet & Greet Lottery for Community & Industry Track attendees. This takes place a couple months prior to the event. Participation in the Meet & Greet Lottery is the only way to receive Meet & Greets at VidCon.
The Meet & Greet Lottery gives attendees an even chance of meeting their favorite creators and ensures that no one waits in line needlessly only to be disappointed when a session is full. It reduces the amount of time people are waiting in Meet & Greet hall lines in general. The good news is that in addition to the Meet & Greet Hall there are so many fun things to see and do while you're at VidCon Australia!
