Killer Sudoko Flinders
Park the car at Flinders Plum picnic area (Daytime access only) given by the coordinates above.
After solving the little puzzle, the coordinates of the cache are :
27 degrees AB.CDE minutes S
152 degrees VW.XYZ minutes E
From the car park is a nice little amble with a bit of a climb to reach the cache location.
Should only take a couple of hours return, or you might like to make a day of it and visit one of the other caches in the area. Take plenty of water, hat, and sunscreen. And be careful of loose rocks.
Now the puzzle to solve before you leave home!
Rules are as for normal Sudoku: numbers 1 to 9 once only in each row and each column, and once only in each 3*3 square. Also the numbers in each coloured shape must add up to the total in the top left corner of the shape.
