Hopefully I can shine light in some way to help.
I was on the phone with the admissions yesterday and was asking about offer dates. I mentioned whether they will be following the same sort of timeline as previous years. The lady I spoke to said offers will be released on December 20th, because they were waiting for WA atars to be released.
From what she proposed, all states sound like they will receive offers at the same time on the 20th...
Not sure about non-standards or rural - there were only 1-2 cases I've seen on here that were emailed their conditional offers back in November.
I'm a gap year rural student from NSW for interests sake
