You have to remember criteria for declaring a TC is different in this basin from the Atlantic/EPac/WPac. Furthermore, outside of NHC/CPHC and Meteo France, no other agency officially warns on subtropical cyclones. Personally I think maybe the BoM could've gone further than just calling it a "complex low pressure area", especially around the time of the 2230Z VIS you posted, but I don't think BoM did anything wrong here.

Re: SW Pacific: INVEST 97P (subtropical?)
I think technically it's in Fiji's area of responsibility (or was).
ETA: actually it's Wellington's.

I don't remember that system at all.

No appreciable difference, as BoM is warning on it for METAREA 10 high seas, and west of 162E it is BoM not Wellington or Fiji.
