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.
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.

Logs
I am currently visiting Wickham/Roebourne on a geocaching trip
The second trig find for today
Back tracking a short way I found a 'private' service road into the back blocks accessing various infrastructure
There were no signs indicating that it was a restricted area so I continued on
This next trig was at the top of a tall rocky outcrop which are a common geological feature of the area
I parked at the base of the hill under a large power line and started my trek up the hill
The slope gradually became steeper and the ground underfoot was slippery, loose, coarse rubble which required careful choice of where to step
There was a patchwork of spikey spinifex which was mostly possible to weave a way between the patches on exposed pathways created by the resident wallabies
Once at the top I was able to follow the GPS on the phone to get to GZ
The vane here is missing and I found 4 separate points where rods had been driven into the ground and were surrounded by a small circle of concrete but no disc was to be found
There were some great views from up here and I took some scenery panorama pics of the surrounding area
