Question about BroadwayCon tickets

I would love to come to BroadwayCon 2018. However, I live in Australia so there is a lot to organise. I just wanted to know how late I can buy the tickets? Do they get sold out or will I still be able to get them at the end of this year? I am thinking about the 3 days pass not the Platinum or Gold.

There's no answer to that I'm afraid. They didn't sell out last year, but they sold out the year before. This year is going to be somewhere in between in terms of number of tickets
