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 access.
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. 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 placing 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.

A test-line!
We noted the high grass, so decided to go to #3 where access looked better - then noted the access track between all 6 trigs, so went back to the car and drove them in order. Muddy and grassy, so not for 2WD (maybe a ute in the dry) - a fun little drive. I sent Samuel out to take the pics, so didn't even get out of the car!
Thanks for the trig point.
Thanks

A bonus six-pack - love it !
TFTC !!
The easiest six trigs we have ever found. We found a little dirt track which took us directly to each one.
Many thanks for these trigs Geocaching Australia
Enjoy the test line trigs.....
Caching in the area we snapped this one on our way past.
We managed distance photos of 2 of them. For this one we drove up a driveway but the long wet grass was under about 3 or 4 inches of water and mud so our long distance shot is taken from the driveway. Thanks.
Made a trip Dubbo and went cache and Trig hunting. Didn't know one could see so many Trig Points clustered together until now. A great day had by all. Hopefully my photos are attached to the correct TP.The Dubbo Baseline is a series of trig markers used by surveyors to check/calibrate their equipment regularly or after service/ repairs. There are numerous baselines or test lines throughout the state for this purpose. These sets of trigs must be checked and certified every two years and the accuracy is +/- 1.2 mm for the distances between them.
