ur right about the 93 paper.. it had, at 46.7 the lowest raw mean in that era, but the was the only time a perfect score was achieved; 120/120.... the student was Anthony Henderson, Sydney Grammar.... google the name to see what he's achieved since
He came equal first with someone else in 1992...check the stats on the Board of Studies.
The hardest paper would have to be 1989, in particular Q8b). There's even a document about it lol:

"Zero candidates in 1989 got it out and that year had one of the largest candidatures for 4 unit in it's entire history, largely due to the super-generous scaling policy for that year for 4 unit maths.
The examiners got back at the 4 unit cohort (and the Technical Scaling Committee) by putting this question in the exam.
James Coroneos (by far the most prolific of all hsc maths authors) had this to say about it:
``This question 8(b) was, in my opinion, far too long and too difficult to be included in the paper as a fair test of the 4 Unit Course.''
If you can do the 1989 4unit HSC Q8b question, you should do well in any Extension 2 exam"
