RFI travel in mid NSW

Dear birding-aussers

My London son is visiting, a keen birder, and wants to get a look at
some of the birds the other side of the Divide, west of Dubbo, ie: out
around Lake Cargelligo, Bourke, Walgett and Nombinnie Nat.Park, etc.

Has anyone recent experience of travelling in these areas – state of
roads, heat, flies, vegetation, wetlands?

Any information would be most gratefully received.

Thanks

Penny, Gloucester
