ESP8266 AT+CIPSTART="SSL","www.google.com.au",443 ERROR CLOSED

Does anyone know why this command won't work with "ESP8266 NONOS SDK V1.5.4" or if there is a version of this firmware for which this command will work.

What are the arguments for the CIPSTART command? I thought, though I certainly could be wrong, that the first one was a URL. "SSL" doesn't look like a URL.
