Omeo to Corryong Road

If the sealed section north of Benambra has not been extended, that makes a bit over 70 km of formed gravel road left.

That'll take you past the International Airport at Mitta Mitta.

If you’re planning to use the road from Omeo to tallangatta via Mitta Mitta, be aware that it is narrow, very windy and very slow. It is a superb drive with great scenery, and with good camping options along the way, but I wouldn’t consider it a shortcut! The dirt road through Nariel was pretty good a couple of years ago - towed a Tvan both ways - and a lot quicker. There was some bushfire damage around Nariel but I have no details. Over Hotham is your other option, and another fabulous drive. Wish I was making those plans...

The Omeo Highway also gets some crazy logging trucks though maybe not so much in winter.
The Great Alpine Rd is also great for scenery but needs to be checked as clear during the winter.
I would take the Nariel road hands down. It's not had the normal snow traffic and is probably in good shape.
