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.

That’s my first impression of this grand structure. It’s been knocked around a bit and mistreated but it’s still standing. I’m continuing my mini pre-work adventuring and I’ve just visited another local Trig Point and this one’s a beauty! A one hour return walk from the end of Prout Road will sort this out. I would have liked to have driven my geo-van up to this. It would have been a good test.
On my map I could see two Mount Petries less than 1km apart which I thought was rather strange.
Do I have time for another Trig visit before work..
Today, I had some time before the family came home and was nearby so I decided to do it. I drove to the end of Prout Rd and began my walk.
I seemed to take the steepest route but I was heading for the peak which I thought was Mt Petrie so I followed the track that headed up it.
When I got to the top, my GPS said I was still almost 500m from the trig point. So then I headed down and along the ridge before finally heading up another steep climb to the trig point.
Coming back down, I took a different trail which was not nearly as steep and was soon back at the car.

After reading the previous log by making tracks. I thought that seeing it was near Bayview which I had found 4 years ago that it would be a stroll with a bit of a climb at the end.
I parked at the end out Prout ST (South) and the GPS indicated 1.5km. I thought that Bayview was a bit closer than that from memory.
After walking about 300m along the bitumen I came across 2 dogs wandering towards me. "Must be someone walking their dogs.", I thought.
No dog owner appeared and the larger of the two decided to walk along with me.
I got to the top of the rise where I remembered Bayview was and the GPS read 1km to go. "Oh well, it can't be any worse than the last climb so I might as well continue."
The dog kept pace with me the whole way down and up and down and up again until I finally zeroed out on the GPS with a Trig point.
Took the photo and convinced the dog (I had named him Tiger) to turn around and head back amidst the sound of nearby gunfire. I was hoping that I was not the target and thought I heard one hit the foliage not far away.
I found a slightly easier track back which missed the steepest climbs but still had a good 100m one back to the top of Bayview.
From there it was a gentle stroll back down to the car.
It was hard to say goodbye to my companion when I departed and he seemed have a forlorn expression on his face. I hope he found his way home again, wherever that was. And I hope he found his original companion dog as well.
Certainly was a good lunchtime stroll which I wont forget for a while.
Great place for a day out or trail running.
Be careful not to stray into the back of the nearby firing range!
