According to DVD Compare, the Australian Blu-ray release is the US R-rated theatrical version. While it contains footage removed from the US PG-13 Blu-ray disc and the UK Blu-ray disc, it does not restore violent footage supposedly cut from the pre-MPAA version, i.e. the original unrated version, to get a US R rating. As far as I know, such an 'unrated' version has never been released officially on home video. (Rod W. 17/3/2009)
