I wonder why the wait for another company has taken so long. I also wonder if possibly a European tour would do well??
A Chorus Line revival played its final Broadway performance on August 17, 2008. The tour played its final performance on August 21, 2011. A new non-equity tour started in October 2012 played its final performance on March 23, 2013. Another non-equity tour launched on January 20, 2018. The tour ended its US run in Kansas City and then toured throughout Japan August & September 2018.
i'm pretty sure it will be coming to Sydney, it's the other cities like Brisbane and Perth that it probably wont tour to unless it is very popular in Melbourne and Sydney [which will be likely].
