This cache has been placed next to the cycle path parallel to Karrinyup Road.
The best (and safest) way to get to the cache is to park on the verge on Duart road, and then walk on the path to get to the cache. DO NOT attempt to stop on Karrinyup road, it is FAR too busy to do so safely!
The container itself is a metal tube about 20cm long which holds a bison tube inside. In order to get to the bison tube, you must first open the lock on the cache.
Before you search for the cache you will need to find three numbers, otherwise you won't be able to unlock the cache and claim your find! [:D]
Number A: The number of the day on which geocaching was first officially played.
Number B: The number of the month in which geocaching was first officially played
Number C: The last digit of the year in which geocaching was first officially played.
That's it! The geocache is hidden at the supplied coordinates,you just need the 3 digit number to open it!
Put the numbers into the combination lock as ABC,starting with A at the top and ending with C at the bottom.
If you are really stuck at finding the numbers, look at the hint and it will tell you exactly where to find them. Otherwise email me! 
Cache should be an easy find!
Happy Geocaching!
