Never heard of some those places you mentioned - Crestwood? Glenwood?
It would be a bit of a drive getting between Baulkham Hills and North Sydney every day, even using the Lane Cove tunnel [and that's if you can afford parking at N. Sydney rates].
Have you thought of other places on the North Shore line like Hornsby? And a lot of people who work in North Sydney commute form the inner west and southern suburbs of Sydney, travel times of 40mins to 1 hr a day. Quicker and more reliable than getting to Woy Woy, I reckon.
