12000 fpm, the instrument proficiency check would also act as a flight review if you were going to do that. If you're dropping the IFR for the moment, a tailwheel design feature endorsement (for example) would also do the trick for a flight review as per the following extract from CASR 61.745: Gobbledegook is a pretty good description of the whole thing, unfortunately, but once you start trying to use it it becomes slightly clearer.
(3) For subregulation (1A), the holder is taken to have successfully completed a flight review for the rating if the holder:
(a) passes the flight test for the rating; or
(b) passes the flight test for an operational rating in an aircraft of the class covered by the aircraft class rating; or
(c) completes flight training for a design feature endorsement in an aircraft of the class covered by the aircraft class rating; or
(d) successfully completes a flight review for a pilot type rating in an aircraft of a type prescribed in an instrument under regulation 61.061 for the class rating;
Outnabout, the situation with low level has changed since CAR 5 rules in that it's now an 'operational rating' along the lines of an instrument rating and needs a proficiency check, similar to what used to be a renewal. They love changing the names of things which just confuses me, but as I said it gets clearer once you have to apply it a few times. Low level rating flight reviews can be combined with your standard HFR or AFR as the case may be, every two years, but you have to include a low level segment which checks the appropriate competencies (much as I hate that word too).
Basically now you get a licence (e.g. CPL), a category rating (aeroplane, helicopter or perhaps powered lift if you fly a tiltrotor!), then you add further ratings and endorsements. To do anything at all you need a flight review every two years which is similar to the old rules, and then there's the extras.
So-called operational ratings are things like instructor, aerial application, instrument, low level etc which require regular proficiency checks, most two yearly, but not all, as you've already said.
Aircraft require either type (e.g. B737) or class (e.g. single engine helicopter or SEH) ratings, and flight reviews as appropriate.
Then you have design feature endorsements (e.g. fixed floats, constant speed prop, retracts etc - again, names have changed for some things to confuse the issue, and gas turbine has been added).
Finally we come to the flight activity endorsements - these don't need a flight test or review, just training - things like formation, aerobatics etc.
It really is a bit of a schemozzle and the more I look at it the less I think it achieves, but we have to work with it. CASA appear to be backpedalling on a lot of things by way of exemptions and ongoing changes, so after much time and energy expended it appears not a great deal has been achieved practically speaking. There are some improvements if you look hard, but they really didn't need to do it this way. Anyway, on we go.
