BASE jumping, also sometimes written as B.A.S.E jumping, is an activity that employs an initially packed parachute to jump from fixed objects. "B.A.S.E." is an acronym that stands for four categories of fixed objects from which one can jump: buildings, antennae, spans (bridges), and earth (cliffs).
Geocachers in the Illawarra now have an opportunity to go virtual BASE jumping and find a cache!

In the image below there are four locations- a building, an antenna, a span and spot of earth. To find the location of the cache you will need to firstly pinpoint each of these virtual locations and then draw a line between the northern and southern location and another between the west and east locations. Where these lines intersect you will find the cache. Of course these are only virtual locations- no need to visit them once you work out where they are.
This mightn't be an exact science so to narrow it down a bit the last two south decimals are 85 and the last two east decimals 11. Good luck!
