I too have the Australian blu. Wouldn’t mind the US Theatrical cut in HD.
I found this 10GB version on myspleen
Conan.the.Barbarian.1982.Theatrical.Cut.1080p.AMZN.WEB-DL.DDP2.0.H.264-ETHiCS.mkv.torrent
Ah yes that’s my upload and it’s taken from a much more recent scan, it looks better than the blu-ray and the missing audio cues and sound effects are restored on it
