Can anybody give me a web page that lists all (or most) of the trig points in Aust.
I don't know if this is too big an ask or not.

Hi Mal
I am no expert with the number of Trig points in Australia, but I would say that the 140 above is
well short of the true number. Australia is a very large land mass and when they were erected in the 1800's, the surveyor had to locate then in a prominent location so they could be seen for many
miles, and then do their calculations from them. Below are a few trig stations that we have come across during our outback travels.
My son is a surveyor, but I can not get the correct number from him, as he is away working in the back blocks of Queensland.
Cheers
Stephen

Hi Graham
In many
places in Australia where there is very little elevation, the trig stations are placed at a point that is the highest elevation of that area. Some very good examples of this are over on the
Yorke Peninsula here in SA, just ask Roachie. When my son was surveying over there, he took us to one area, south of
Port Hughes. As you can see, this modern day trig is placed on the highest elevation point, and as you can see, it all looks very flat.
Cheers
Stephen

There are a variety of trig points established by a variety of agencies. There are various orders of accuracy. First Order being the most accurate. These days with the Surveying type GPS systems they are not as important as they once were.
Each state has a trigonometrical network and should have the details for all their trig points including coordinates and access notes. Each state land departments or whatever they are called in each state these days will hold these records or advise you where they are now archived and who controls those archives.
At a Federal level, the Division of National Mapping now under the wing of Geoscience Australia had records of th trig stations established by NatMap and other federal agencies, so they would be your best bet. They would be in the geosdesy section.

Further to my post.
From the Geoscience Australia web site:
National Geodetic Database (NGDB)
The NGDB is a national archive of about 23,000 geodetic survey marks of national interest, in Australia and its external territories (including Antarctica).
Coordinates of these marks are held in the Geocentric Datum of Australia (GDA) as
well as the two previous versions of the Australian Geodetic Datum (AGD66 and AGD84). Not all stations have coordinates in all datums.
State and Territory agencies can supply recent and additional information for their area of responsibility.

Equinox, what can I say? That is precisely what I was looking for. Thanks. I'm a bit embarrassed though as I am a Geocacher myself.

Mal, I hoped you and Di were catching fish up there. Not sure why you would be embarrassed about being a geocacher. Most just haven't been introduced to the concept. Enjoy
Darwin, seems that those who went to Mt Ive enjoyed the event. Catch up some time.

John I wasn't embarrassed being a geocacher, just the fact that it was there under my nose and I didn't see it.
We are leaving tomorrow and will be going to the
Gawler Ranges on the way through. I haven't been on "our
forum " lately due my email bouncing.
Will sort it out when I get back home.
Cheers M.

We are to head back on a trip to the Eyre Peninsula for a few days from the middle of next month. Just give me a call about the KKOG
forum if you need. I knew you wouldn't be embarrassed about Geocaching, mate, it would take more than that.
