The Blue Mountains in NSW are not part of the Great Dividing Range. As written earlier, the GDR seperates the western flowing rivers from the eastern. All rivers in the Blue mountains, and indeed even some of those west of the Blue Mountains flow to the east. — Preceding unsigned comment added by 220.127.116.11 (talk) 08:08, 8 November 2005 (UTC)
You seem to be referring to the watershed line or demarcation; however, the GDR is not just this line, but the surrounding mountain ranges as well. By definition, there will be both east- and west-flowing rivers emanating from these ranges. The Blue Mountains are quite commonly and unproblematically included as a range within the GDR.--cjllw | TALK 08:39, 8 November 2005 (UTC)
The original poster above is correct: The Blue Mountains are NOT part of the Great Dividing Range. The very name of the GDR contains the word "Dividing" - and the thing which is divides are the western and eastern flowing rivers. The Cox's River, for example, starts West of the Blue Mountains, and yet flows to the East, past the Blue Mountains. CptAnonymous 15:24, 8 September 2007 (UTC)
Would be good if someone knowledgeable could write about the geological history of the Great Dividing Range. Apparently not due to tectonic plate collision, but caused by the gradual passage of the continental landmass over a volcanic 'hot spot'.
It is actually caused by neither though locally some volcanics do create mountains within the range. I will see if I can find something in the next month or so. Yendor of yinn (talk) 11:56, 15 September 2012 (UTC)
