To work out where (exactly) the cache is you need to complete the following Sudoku. With the pink highlighted horizontal squares giving the Latitude minutes/decimals, and the blue vertical highlighted squares giving the Longitudinal minutes/decimals. Reading left to right, top to bottom.
So the cache is at:
S33º 4x.xxx' E151º 1y.yyy'
Maintenance of this cache, if required, will be by 'local' cacher (Dave) Juddda - tho he had NOT found the original, and has been given NO clue for this one. He is more than welcome to work out where, and Find it!
Some of the contents of the original cache, GC3H9B9, were transferred to this one.
