...for example with a gf internal conversion you need to fire rate dividing walls, is this required for leasing individual bedrooms? Say you find an old fibro place near a uni in Syd and lease to 3 or 4 students??? Fire rating required or not?
Yes you'd need fire-rating between them. e.g. 2x attached 30 sq m self-contained units are allowed. Ive never done it but the SEPP seems to say it's ok. See below:

Note. Principal and secondary dwellings will be classified as class 1a or class 2 under the Building Code of Australia depending on the configuration of those dwellings.
CLASS 2 DWELLING: A building containing 2 or more sole-occupancy units each being a separate dwelling.
The only reasomn to do this of course is for student accomodation with more than 1 kitchen.
