Brother in Jail in NSW

My brother is currently in Jail in NSW at Cessnock, he had a court date at the start of the month I saw online and then I confirmed he was in there from the inmate location phone after the date. I live in QLD and wasn’t able to make it to the court date He however won’t return any calls to any of our family a month or so prior and even no showed a zoom meeting my mother set up with the prison. Is there any possible way to find out his charges/release date, I read online it can take 6 weeks for court transcripts so don’t want to wait that long hopefully there is an alternate way?
