If you follow the tracks and with a little bush bash, the cache is not too hard to find... but can you find the signing log?
DO NOT attempt from the Highway, as there is a railway line to cross. BEST to park in Railway Terrace... where you can find a few tracks into the bush.
Please put the log and cache back exactly how you found it. Good Luck
