I don't get how you calculated that Orion will be overhead in about 10hrs. I need to understand that math.
I just said 19 + 5 = 24hrs = 00 hrs, add 5 (approx) for Orion = 10hrs. Orion transits about 10 hours from 4pm (AEDT) which makes it about 2am AEDT. Sounds about right for this time of year but I haven't been out at 2am lately.

Older Planispheres used to have RA on them but most current version do not which is a pity.
