A little history for anyone interested to know.
For the past 6-7 years Griffith GC cutoff was typically 99.80, Nathan 99.75 (with the occasional 99.70 top-up offers).
In one "special" year, iirc 2020 intake due to the peculiar half-sized QLD Y12 cohort fewer applicants, both GC/Nathan dropped to 99.50.
For the 4 years USC has existed, its cutoffs were 99.35, then 99.50, then 99.60 with a few 99.55 top-ups.
Last year 2022 intake was a disaster. Due to the Covid situation IB was over-generous with their marking churned out double/triple the usual numbers of IB 45/44s. I believe this was responsible for pushing GC/Nathan to 99.85, USC to 99.80.
Hopefully this year if IB comes down to normal GC/Nathan/USC will come back to the typical 99.80/99.75/99.60, less 0.05 for any top-ups.
