That sounds good, thanks a lot! Looks like it isn't as long as I envision it to be.
Would it be too ambitious if I were to also make a quick detour into Blue Mountains, just to do a quick sightseeing / taking of photos, since I'd have the car for a full day? This would be after using your suggested drive to take the Hume Highway into Sydney.
