Cooma to the coast via..

Hi all

Will be driving form Cooma to Batemans Bay Monday 17th, wanting to avoid the bitumen but not wanting anything low range, so I was thinking of a route via Numeralla and Nerrigundah, or Numeralla to Cobargo..

If I had more time and was travelling with other vehicles, we would head straight to Bendethera Valley, but as we will have the Prado loaded to the gunwales with kids and bikes etc and we are not looking at spending all day in the car doing endless low range climbs etc..

Has anyone travelled these roads recently? Are they suitable for a basically standard Prado shod with A/T's with only about 40% tread remaining? (I know, I know...new tyres are coming just as soon as we get Christmas and this holiday paid off the Visa..) Any river crossings or long climbs/descents that will have the wife cursing me for not taking the bitumen?

Thanks in advance
Richard
