You may like to think about this route from Coonabarabran to Dubbo. Some lovely country road, just need to be a little careful of wild life when going through the Goonoo State forest. It is actually 10 kms or so shorter. https://www.google.com.au/maps/dir/Coonabarabran+NSW+2357/Mendooran,+New+South+Wales/Dubbo,+New+South+Wales/@-31.8321943,148.8380219,9z/data=!4m20!4m19!1m5!1m1!1s0x6b0906e540ff0ed5:0x40609b4904378d0!2m2!1d149.2774205!2d-31.2739131!1m5!1m1!1s0x6b08d5a0f012263d:0x40609b490437b40!2m2!1d149.122213!2d-31.823129!1m5!1m1!1s0x6b0f71b04ca4913b:0x50609b490442530!2m2!1d148.6094976!2d-32.2438146!3e0Have a great trip
