Queanbeyan to Bredbo

You can go Qbyn to Bredbo via Captains Flat and Jerangle, but it is all gravel (good surface though). Also, you can go Qbyn to Burra and then to Michelago, bypassing the ACT, again, gravel roads. But why bother? You can go Qbyn along the Old Cooma Road to Royalla, and then down the Monaro Hwy. Yes - it is in the ACT, but it is all in the country and only about 15 km before you are back in NSW again. And the last route is sealed road all the way.

My understanding about blockades is that you are allowed to travel through the ACT, as long as you do not stop in the ACT IF there is a blockade in force. I was almost commuting to Sydney from Cooma last year, and I never seven saw any efforts at blockades. I heard on the TV a couple of days ago that ACT police were randomly stopping cars coming into the ACT from the North, but I have not heard anything about road blocks elsewhere. I seriously doubt that you would have trouble going Qbyn to Royalla and then down the highway .

Yes, you can.

Queanbeyan - Old Cooma Rd - Burra Rd to Michelago then Monaro Hwy keeps you out of ACT.

Instead of Burra Rd you could stay on the Old Cooma Rd and join the Monaro Hwy at Royalla but it is arguable whether or not you're in the ACT or NSW as the Hwy at that point seems to be the border.

Edit: Erad posted while I was doing my map!

The border is the railway line which, at Royalla is only about 100 m East from the Monaro Highway.

There are no blockades in the ACT or at the borders - if you have been into the Greater Sydney area you have to "self" report and "self quarantine". No issues from Quenabeyan.

I would just drive down Lanyon Drive to the Monaro Highway and then south down to Bredbo. If you are worried - then down past Googong, Burra and south the Monaro Highway
