I understand this language.
It says PSLV-C-38 launch is on this month 23rd at 9:29. Yes India is 4:30 hours behind and that would be 1:59pm AEST.
PSLV-C-39 launch preparation starts from 28th. apparently one of seven satellites of IRNSS supposed to be part of C-38 was not communicating properly. It will now be launched by C-39
