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.

Logs
. I can't imagine why this trig has not been logged before. It's not the easiest trig to get to, but there are harder terrains that have been conquered to log a trig. But nice it was left waiting for us to get to log first 
. So thank you to all those who let us be first 
.After studying google maps we set off. We tried to approach from Brooks Road, but
private property that direction. So we headed to Lake Road, which we had suspected all along would be how we would get to the trig. We had just hoped there would be an easier route than up the escarpment.We parked at the bottom of the escarpment, looked up at the STEEP incline and slowly set off, up, up and up. It was slippery, so we changed course and headed more diagonally across the incline. Once we reached the top (relief that what we could see really was the top of the incline and not a force top) the going got much easier; in fact very pleasant with magnificent views to Lake George. I think the views from up there are some of the BEST views of the lake I have seen. We followed the tracks to the top.
The trig is in good condition, with a good paint job, so someone visits to paint it. Next to it is a circle of stone with a trig metal bit in the middle, and there is another concrete slab with another trig metal bit in the middle.
After admiring the trig it was down we headed. The walk to the escarpment top again pleasant; in fact better than the other direction, as walking towards the lake we could admire the views. Then we faced going down that steep incline, as slip and you mightn't stop until the bottom. In some ways going down was worse than coming up. It was about 200 metres between top and bottom, but much of it, a VERY steep 200 metres.
Fun to do.
