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.

And there are hundreds of signs saying do not drive tired so geocaching helped with that.
The day turned eventful after gashing my leg at a cache, putting a tiny hole in my font tyre returning from Madura Cave then at Norseman the motel i had booked with did not have me on their list, so managed to get a room at the pub. They do say they come in threes.....
I parked up on the side of the road for the start of many trig points.
I cleaned quite a few so any writing could be seen rather than just a mound of dirt with a pole.
This Trig was a very quick find and also has a quandong tree next to it.
Thanks for the trig cache Geocaching Australia
This one was a bit different and had a battered plate at the base of the pipe and rocks around it.
Thanks. Although our plan didn't work and horror driver passed us again while we were here.
I found meself on the boring stretch of Eyre called the 90 Mile Straight.
A line of trigpoints promised to liven up the boring drive
And here I found number eight of a line up of fourteen trig points published on GCA that lie in a straight line across the Nullarbor, stretching east to west
Only the ten that lie alongside the 90 Mile Straight are easily accessible.
The other four line up to the east of Caiguna and present much more of a challenge to find
Another quick stroll from the geomobile parked highway side and I had the photo I needed
Definitely different with its metal cover !!
And of course some dimwits have had to dent the metal with rocks
Hooray !! The idiots have discovered stone tools !!
The rest of us did that back in the Stone Age and have evolved

A quick find on our trip west after holidays in SACheers
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 "50 metres to next". An easy walk through light woodland, and I spotted the pipe base set in concrete and one star picket with remnants of twitched wire which would have been the support stays for the head. There was no marking on the base but it was probably NMF121 as the next one down the road was no NMF122.
I rate this a Difficulty 1 Terrain 1 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.
