The 19th-21st of December offers were for local applicants,
yummo11. As an interstate applicant, your offer round isn't until early January.
Lauren2000 is a local applicant, so I suspect her friend is too.
Unfortunately, you just have to wait a smidge longer, but your score combo is certainly competitive. What was your confirmed ATAR? I think your predicted was mid-99.xx wasn't it?
Lauren2000 can you keep us posted on your friend? The reason I ask that is I have personal experience of being told I have an "offer pending" and that I'd have it by "the end of the week" and it was an absolute lie and I didn't even come close to getting one (for 2017 entry), so I sincerely hope they've not left your friend hanging like they did me.
