This is what I make of it.No doubt,only partially correct.
'Yabbie Creek' is a fictional place.It's a setting for Channel 7's 'Home and Away'.
Also YYAB is not the ICAO code for the aforementioned Yabbie Creek (because it's fictional).YYAB is Yackabindie,WA.
Moving along,Ch.7 have been promoting a 'plane crash' in an upcoming episode.So,the OP is,in effect,attempting to promote a Ch.7 show by posting a description of a fictional prang.Perhaps to get 'viral' hits on search engines ?Apparently,the 7 promo depicts a white Bandit (I don't watch soaps).As to why VH-EQB is mentioned,I have no idea.
