AU915 - Maximum transmission power 25 mWatt

I’m curious if anyone has done further analysis on this issue. i.e. Is LoRa modulation in Australia actually limited to 25mW.

More specifically has anyone done a technical analysis of LoRa Chirp Spread Spectrum modulation in relation to Part 58 of the ACMA regulation (The radiated peak power spectral density in any 3 kHz must not exceed 25 mW per 3 kHz).
