>From what I can gather from
http://www.comlaw.gov.au/Details/F2014L01253
the details are hidden in the standard "AS/NZS 4268:2012". The scope
here:
  http://shop.standards.co.nz/catalog/4268:2012%28AS|NZS%29/scope?
shows the existence of an appendix "B" titled

 "DYNAMIC FREQUENCY SELECTION (DFS) AND TRANSMIT POWER CONTROL (TPC)
  REQUIREMENTS FOR RADIO LOCAL AREA NETWORK (RLAN) TRANSMITTERS
  OPERATING IN 5250 TO 5350 MHz OR 5470 TO 5725 MHz"

But I'm afraid you'll have to buy the standard to get the full details...

Given hysterical raisins, and the general tendency to reference ETSI
standards and ERC decisions, I'd say that DFS-ETSI is more likely.  Why
would they use FCC rules?

But it should probably be kept aligned with the NZ entry, which
currently is DFS-FCC.  Don't know the source of that, though.  Could
very well be wrong...  Ref the "EN 301 893 V1.7.1" alternative given
here:  https://gazette.govt.nz/notice/id/2015-go694
