Sydney Hilton bombing March 1978 PODs

http://en.wikipedia.org/wiki/Sydney_Hilton_bombing

OK, WI say there hadn't been a bombing of the Sydney Hilton, but instead if ANADA MARGA sect members had infiltrated the building and taken the CHOGM ministers hostage a la Munich 1972 or Princes Gate 1980 ? How would the Australian SASR, ASIO & other counter-terrorist forces have responded ? What could've been the likely outcome of such a terrorist attack on Australian soil ?

Also, as noted in the Wiki article, no official inquiries were ever conducted on the bombing OTL due to Cth govt disapproval, despite 2 NSW govt requests in 1991 & 1995. WI such an inquiry had in fact been held ? What could've been the results ?
 
I don't think the chicken stranglers were ready to do this sort of assault in early 1978, they didn't reach IOC with this sort of thing until the very early 80s. I'd tell you exactly, but I'm moving in 3 weeks and my books are packed into boxes.
