Pooncarie NSW westward to the Silver City Hwy

Yes, you'll have no issues Warren. Cross the Darling and take the High Darling Road north past Mullingar and then follow it as it turns to the west (Polia Road runs off to the right and heads north). It skirts across the top of the mine and becomes Nob Road which you follow down to meet and turn right on the Old Roo Roo Road down to Nearie Lakes Reserve. You'll cross the regulator on the western side of Nearie Lake and not long after meet the Old Broken Hill Road. Turning right will take you west to the Silver City Hwy south of Lake Nalia or you can continue north to meet the SCH on the southern side of Lake Polpiltah.

These are all station country roads and are generally well maintained as they have to accommodate large trucks and machinery during harvest and shearing times (or to haul out goats). Popiltah is a good place to camp but a bit noisy with trucks heading past. I prefer to get into the bush on the left hand side of the SCH about 500 metres past the Popiltah rest area. You'll see a gravel scrape and dam there with a good track driving in about a km along a flat.

It will be very dry and hot out there so if you're doing this in the near future, take plenty of water with you. I don't know what flow got down the darling this year so have no idea if there is water in the lakes or the Annabranch.

As long as it's dry, those roads will be ok for 2wd.
The haul road will have triple road trains doing about 80 kph along there throwing up stones all over the place with so many wheels, so give them a bit of room.
