With Pawel and Sylwia who got me a ticket on 2018-12-06 for $140 and a booking fee. I'd missed seeing this in Chicago a few years back. The Sydney Lyric theatre was packed; we were in row D near the centre, which was perfect. I don't think I'd been there before. Apparently it seats 2000 people but it didn't feel that big. We had a light dinner at Gojima beforehand.
All you need to know is at Wikipedia. Briefly, it's a product of the South Park minds (yes, it's scatological with something to offend everyone) and has been running since 2011. It explains while it entertains! — which sometimes made me wonder what their game really was. Many nods to 70s/80s geek culture (Star Wars, Star Trek, Douglas Adams, ...). We all enjoyed it. The cast seemed strong to me, but I don't go to many musicals.
Reviews are legion. John Shand.
