Bulli Pass, Picton Rd, Hume, Federal, Monaro, Snowy Mts, Princes Hws should be a bit faster thanks the Princes. Certainly easier. Not as scenic and less nice places to stop though.
My impression is that the Princes Hwy is of lower quality and with a lot more traffic than the Monaro and Snowy Mts Highways and of course the Hume and Federal are divided roads. Your prospects of spending a lot of time cruising at 100 km/hr are much higher inland.
It takes too long to get there but worth the drive, 35 years ago I could do Carlingford to Cooma in 4 hours Flat in my Suzuki Seirra, total disregard of speed limits, I now do Central Coast to Cooma in 4:40 knowing I Need my licence.(northconex should save another 5-10 minutes) Monaro hwy. Is heaps better, but I do miss the tight banked bend just south of Numeralla river, if you look in the Paddock adjcent to the new bend you can still make our the old embankment.
That's just inconsiderate to other road users plain and simple... Naturally this is from truckies who drive the road (i.e. hume) all the time. So the know they could have maintained a gap to the rig in front on the flat, then timed their run to close that gap uphill as you describe, then make the overtake on flat/downhill... But of course the other trucker sees this and thinks "I ain't git'n passed by no stinkin Kenworth", and speeds up. It's all in the movie: "ain't nuthin like a caterpillar engine"
