The 20 kts was supposed to be introduced only for noise sharing modes, but it got f@rked up somewhere along the line and 20kts was adopted across the board.
Not sure if it was ASA/CASA/QFA or AAA - probably a combination of all 4.
From this thread it appears that ATC in Melbourne tell the aircraft crew what their crosswind limit is? Surely that is a decision for the Pilot in charge, according to the aircraft certification and handling pilots qualification.
