This is the way
A straight forward single waypoint multi, that take you into the mysterious and seldom visited O'Hara's Creek area of Kenthurst.
The posted coordinates take you to the trailhead. From there you will descend into darkness and the junction of O'Hara's Creek.
At WP1 you will find 2 pairs of numbers with the format ABCDEF GHI. (Look around!)
The cache can be found at :
S 33 (E)(A+E) . (B-G)(C)(F)
E151 (A-B)(A-B) . (B-C)(D-B)(H)
(It does not matter which pair you use - close enough is good enough)
