Bachelor of Dental Health Science (1577) This has the course list for the undergraduate component of the dentistry course. You can click on any of the subjects to view their course profile for a detailed breakdown of each subject; course content, classes, assessment etc. You'll need to look at the 2018 profiles as currently the 2019 ones are yet to be released (they won't be released until late January or early-mid February, I'd expect).
As for transfer credit, I'd definitely expect you'd be able to get credit for the first year chemistry courses (assuming you covered this in your science degree) - you can apply for credit via the following link once you've received a place offer and enrolled:
Griffith University: Single Sign-On
There are only two dentistry-specific subjects in first year. Based off a brief scan of the course profile it doesn't look like you'll get any clinical exposure in first year (only labs, practicals, virtual simulation labs and communication skills classes).
I've personally done all of the first year subjects other than the dentistry-specific ones. I'd be happy to write a brief overview of each of them if requested, though keep in mind it's been a few years since I did them so if there have been changes to teaching staff / course content then my information may not be 100% up-to-date. A brief look over the course profiles tells me not much has changed in the way of content or assessment.
ETA: I'll be moving this and further non-accommodation-related discussion to a different thread shortly.
