Non-standard radio phraseology can be very dangerous, it was a major contributor the night the TAA B727 hit the Canadian Pacific DC-8 at Mascot.
Non-standard (by Australia) phraseology ( of which CAA/CASA and ASA had been aware of for years, also resulted in a horribly close near hit between an executive jet and an airline aircraft (from memory a DC-10) of the NSW coast.
See Annex10, Vol.11.
