Basically all the same maps with a couple new ones. His WA maps are bloody useless more likely to get lost following them then find gold. Most of the tracks and landmarks he uses are nonexistent, and basically all of them spots have current leases on them. Better of with gold and ghosts, it has all the same info plus more but with more detail and better directions.
You really don't need either though as the best method in WA is to follow the geology. Download the 250k geology maps on the wa govt website then overlay some mines on it. You will quickly see trends and patterns, just trying extending the pattern you see.
