Priority Boarding is an interesting one, overall, I've found it to be good in general, but in some ports (e.g., HBA and ADL), I can't tell if it's being poorly enforced or I happen to take flights with high premium loading. In SYD/MEL/BNE, I've found that I can gather my things in the lounge when boarding is called, and more often than not I just walk straight on in before general boarding starts. There was a recent instance where a dozen of us or so got final called on a delayed flight out of MEL though... was graciously allowed to put my luggage in the Business overhead (was in Econ X) but others behind me weren't as lucky...
One thing not covered in the original article is the baggage check-in experience which I've found to be wildly inconsistent. Terrible at MEL, I think the only port where I've had generally good experiences with was in SYD? Priority tagging hit and miss, although the in-app baggage notifications are great (I believe QF might have their own system but I've had not personal experience with it).
Another 'negative' is the lack of ways to earn status credits on the ground. Aside from the marginal Coles earn, there really aren't really any other opportunities (there was a credit card one I think two years ago?). It may be just a one-off from QF, but I will have 'accidentally' reached Bronze from 4 flights this membership year from random status promotions and Green tier.
