Description
A Trig Point is a virtual cache which requires a cacher to locate the Trigonometric Station at GZ and to photograph it.
Official Code: Permanent Mark PM58001
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.
Access: This is within the Univeristy of Newcastle, Callaghan campus, The 'trick' is to find somewhere to park, especially during the week, so it may be best to start at Newcastle Test Line PM58003.
Logs
Parked in the uni carpark and walked along this old test line. The test line is younger than the uni so it would be interesting to know if the uni grounds extended to this point when the trigs were built and if they had a secondary use of helping the students learn to use the instruments.
Doing a round of caches in Newcastle and saw at least as many GCA caches (mainly trigs) in this area as GC caches, came for both and conquert most.
While staying near Newcastle we went on a GCA cache finding tour around the area and this trig was one we found. The required photo has been added to the gallery. What a huge University. TFTT

Caching in the area we came across this trig and snapped the required pic which is added to the gallery..

#GA2658 - 11:35; Day three of the 2018 Oz GeoMuster mission with Sol de lune. After a day hitting the geoart trail put out for the muster with Sdl and albida33 yesterday, today was all about finding GCA caches and perhaps picking up a dragonZone or two in the process. The plan for the day was to start in Morisset (naturally enough), work our way around Lake Macquarie and in to Newcastle, then on to Maitland and Abermain before heading back to camp. There had been a change of plans when there was a heavy overnight fog which left our tarps quite wet, so we decided to hit the trail, then return to camp to collect our swags once things had dried out later in the day, before heading for points north. We had finished collecting trigs around the lake and were now in the suburbs. It was nice and quiet at the University today and we were able to park close by to the trig, the third of four in our first testline for the day. TFTT Geocaching Australia

Day three of an Easter trip with LuckyL10n to the 2018 Morisset Mega. Headed up via the northern beach suburbs of Sydney to grab a few trigs and dragonZones along the way. From there it was a trip around the lake to find a good assortment of trigs. A great day out while heading further north.
The first of two testlines we did today. No problems with this one and the trig was soon snapped. Very quiet at the Uni on Easter Sunday.
Another trig and another dragonZone crossed off. Thanks for the fun....

A trig power-trail! We're up for that..... I thought it might be quiet at the uni on a Saturday lunchtime, but the place was packed - we got stuck in traffic!

Grabbed this one and TP5620 from the same stop. You can see PM58000 in the background of our shot for this one. Thanks.
On my way to Cams Wharf area for a cache of a particular D/T rating (after staying overnight with the older son in Newcastle) I remembered the Newcastle Test Line series of PM/Trigs, and manually loaded them into the GPSr. I had hunted for a geocache near one of them years ago, (UNIque, in 2012).
I had a waypoint in the GPSr for a potential "Herbaria", but I probably had mislabeled it; and it would probably actually be a Medical Museum, that I will have to come back for.
Anyway, I parked in the Student Nurses parking area, and took a short walk over to the concrete pedestal survey marker PM58000. And then walked down to this one, PM58001.
Photographed at 1026, and noted the black cover on top identifying it with "NSW Trig Station, Do Not Disturb". The name plate was still there.

As detailed by rogerw3 there is a cover on the concrete pedestal stating: "NSW Trig Station, Do Not Disturb"
Out in Newcastle for a day's trigging.
While these are not registered as Trigs and do not have TS numbers recently the PVC white caps have been removed and replaced by the triangular aluminum instrument mount familiar on Trig Stations. Further a new type of cover clearly marked 'NSW Trig Station' is protecting the mount.

Is it? Isn't it?
Let's say no based on what's been written and call it a day.

Isn't that what these points are doing?

Found these quick four today on our way home after caching around the lake. Interesting to have four in sight of each other. You must be right the Trigs must be for surveying students.
If you look close at the picture you can see the other trig behind it.

These Permanent Marks are part of the Newcastle EDM Testline. Surveyors use these testlines to calibrate their instruments.
They are not trigs.

Found this trig point while working in the area.
It seems that this series of Trigs may have been set up for the surveying students at the University of Newcastle.
There are four Trigs within a short distance named Newcastle Test Line PM58000-58003
