Brolga Bill's Puzzles
Brolga Bill decided that, instead of making all the puzzles for the Mega difficult and different, he would construct some that were grouped into types, that started easy and worked through to moderately tricky. Each type has five puzzles in its series.
By this technique he hopes that some cachers who normally would not look at puzzles, will have a go at these.
Good Luck.
Co-ordinates
We use co-ordinates all the time in our caching. So being able to know about them, convert them and work with them is important.
There are several ways of doing these type of calculations on an odd-shaped spheroidal earth that can lead to small errors creeping in, so if the checker is not spot on, you may not have it incorrect. Unfortunately, the geocaching checker does not allow any errors. You might need to alter your answer a few units.
The Puzzle
We weren't too sure where to put this one. It was roughly 0.4771km from the starting co-ordinates, and about 0.3612km from a final spot just up the main road at S36 0.596 E146 28.845. Just a hint you can ride/walk/drive to the the final without entering any private property.
