Geocache Description:

Great Aussie Icon Hunt # 5.8 (Canberra to Darwin)

Great Aussie Icon Hunt # 5.8

Round and round they go, and have done such in Australia for almost 2 centuries.
Yes I’m talking about the Windmill – an Aussie Icon seen all over Australia.

Windmill – Aussie Icon

This is one of a series of great Aussie Icon hunts. Travelling around Australia you undoubtedly see windmills: Dead ones, Rusted ones, High ones, Spinning ones, Coloured ones, Huge ones, all seen along the roadside, adjacent farm houses, along river banks, in gullies, in country town parks, in museums, in fact wherever…

This series of geocaches is designed to help you when travelling around Australia, by breaking up the trip, and to discover a bit of a history lesson as you seek windmills in locations with a written history of the windmill and/or local region adjacent.
With each of these trips, I’ll be giving the actual coordinates of some of the relevant windmills along the route – you then have to visit them enroute and determine the vital statistics and any other required info at the location. This will then be put into a formula to determine the final location of the cache. All windmills are accessible by car (no bush bashing required), they are all just a few metres off the highway, or in the centre of towns you will pass through, eg town parks. If there is limited access (to the base of the windmill) due to the time of day a park closes, I’ll mention that for the relevant windmill. All can be easily seen from road though.

Street view could be useful .........
Use that (& your time machine) and all is revealed, 100%.

In many of the windmills, you will be required to count the number of blades on the fan. This will be difficult to impossible depending on the strength of the wind.
Therefore, a digital camera IS ESSENTIAL.

These windmill hunts are in pairs, one from each state’s/territory’s capital city to Canberra, and one separate return hunt. So, for this particular hunt, the “return” is "Great Aussie Icon Hunt # 8" – Darwin to Canberra
GC63GEV - Great Aussie Icon Hunt # 8.

V = (AA-FA-MC)


Finally, as with all windmills, from time to time a blade may fall off and you may see the windmill before it is replaced. So, count how many blades should be there. (unless told otherwise).
Feel free also to contact me beforehand and/or on route to confirm details or any other query you may have on the way, or to be prepared. Remember, when plotting the location of the next windmill, it is generally on a main highway or in a town somewhere, never off in the bush or beyond the black stump. There may be the occasional wind farm.
