How do I convert a cron expression from AEST to ACST?

ACST is currently 30 minutes behind AEST. Subtract 30 minutes to the hour and minute field, and shift the day-of-week if the time crosses midnight. For example, 0 9 * * 1-5 (weekdays at 09:00 AEST) becomes 30 8 * * 1-5 in ACST.

What is the time difference between AEST and ACST?

Australian Eastern Time is UTC+10 / UTC+11 and Australian Central Time is UTC+9:30 / UTC+10:30. Right now aCST is currently 30 minutes behind AEST.
