Not sure the map still shows correct...if going to Boonah, turn off just near Kalbar towards Moogerah, it's a nice drive around the dam there, then once past the dam you turn right towards Mt Edwards and follow the back of the dam up to Governors Chair lookout, I don't go on the Cunningham highway at all other then driving to Boonah or Kalbar which is usually a meet up point for me on that drive.
