Description
A Trig Point is a virtual cache which requires a cacher to locate the Trigonometric Station at GZ.
A trig point (also known as a Trigonometric Station) typically consists of a black disc on top of four metal legs or concrete pillar, resembling a navigation beacon. It is also accompanied by a metal disc, which is located directly below the center point of the tripod or on top of the pillar itself.
Along the Eyre Highway they typically consists of a black rectangular cross on top of a two piece metal pipe which sits in a slightly larger pipe base set in concrete which usually has an alpha/number code set into the concrete. There should also be a "Warning - Standard Survey Mark" placard on a metal post near the base. Originally the top would have been guyed by three twisted wires running to three star pickets. Alternatively there may be a "Warning - Standard Survey Mark" placard on a metal post and a bronze plaque set in concrete usually within 1.5 metres of the placard.
Trig points are generally located at the top of hills or points of prominence in the landscape. Many provide unique views and challenges, with some being difficult to get to.
These points were regarded as valuable to surveyors, providing reference points for measuring distance and direction, and assisting in the creation of maps.
To log a find on the Geocaching Australia website, you will need to include a picture of the trig point, along with your GPS receiver and (preferably) yourself. Long distance / telephoto type pictures are against the spirit of this cache. You are encouraged to leave a description of your journey in your log to help others in finding the trig point.
The original collection of trig points has been sourced from Geoscience Australia and may contain inaccuracies.
Please respect local laws and regulations when searching for trig points. If you believe that a trig point is located on private property or in a dangerous location, you may archive the cache, by clicking on Log this Cache and place an "Archived" log on the Geocaching Australia website.
If you feel that you can add to the description of this trig point or adjust the difficulty / terrain ratings, please feel free to edit this cache and amend the information suitably. Vandalism of the cache description or other information will result in your account being terminated.

Here was another excuse to dash off into the scenery.
Somewhere out in the thick road side scenery was a rusty trig, in pieces with its top fallen off !
TFTTP
A quick wander, hopped over a couple of bits of wayward tree and there we were. In and out in under 15 mins.
I hadn't made a real find since Ceduna, but I'd been looking at all these benchmarks in NT, SA and WA. The WanderingMrs had set a distance limit of 300 metres if I wanted to hunt down more than one, and until we went down the Eucla Pass they were all further away or on top of ridge lines, not particularly accessible.
Once we hit the "Ninety Mile Straight" they became very accessible. I parked on the edge of the road again on a good wide verge, and the Explorist said "220 metres to next". A slightly harder walk through light woodland made difficult by a large number of fallen trees, and I spotted a complete rectangular trig station on a short pipe upside down on the ground, next to a longer pipe inside the base pipe set in concrete. The short pipe had come unscrewed from the top of the long pipe. There were also three star pickets near this one.
I rate this a Difficulty 1 Terrain 2 cache, and if there was a GAFF rating of 0 this would deserve it. I did a "GoTo" on the Magellan Explorist but left it set at 2.5 Km scale. I didn't do a "Navigate To" on the TomTom, but when the icon appeared on screen about 900 metres out I used it to determine where to stop and where to find the Trig Point.
