Note: This cache is generaly only accessible between 5am Monday to 9pm Friday. At other times, locked gates MAY prevent access to GZ.
This cache is a two-step multi. At the posted co-ords, you should find a four digit number on a green background. Labelling these 4 digits A, B, C and D, the final location of the cache can be found by solving the following. I hope you remember the order of operations from school!
Subtract the result from the South Co-Ords: C^D-B-A+sqrt(B)
Add the result to the East Co-Ords: AxD+B-C
The final cache location overlooks the Flemington Car Sheds, which is one of the main train maintenance facilities in Sydney. Bring your owm pen.
