That cut off is generally used for internal law transfers at UNSW, and is not indicative of the mark required for an external transfer into law at UNSW. External transfers also take into account ATAR and LAT scores.
There are two kinds of transfers, internal and external. Internal changes course within the same uni, whilst external is from one uni to another.
If you want to do a double law degree, and are set on going to UNSW, you could do the non-law degree for a year, and if your marks are in the distinction range apply for an internal transfer and continue with a double degree the following year with no loss of credit points. At UNSW, an internal transfer only takes in account your WAM, whilst USYD takes into account both your ATAR and WAM.
If you are more set on doing law, you could go to another uni and be safe in your law degree there and apply for an external transfer after 1 year of study. Generally speaking, external transfers into UNSW are harder (given that there is no guaranteed 100 spots like internal transfers) and you will also be now competing against all students in both year 12 and 1st year also doing LAT for entry. The only risk of increased study time for an external transfer, is if you cannot get credit for the units you've already done at your other university.
