Hi Guys I found this right on a walking track in a National Park yesterday: Image Link
Do you think this would still be used? and how old would it be?
Cheers, Art.

The PMG was abolished in 1975 so it's probably no older than that.

Can't say if it would still be in use. I guess it depends on the area it serviced, or whether it perhaps serviced a communications tower facility of the era.

I have a fence line with rows of those. They went to a yellow treated pine pole from those. Prior to that is was single wire strung between trees.

I have no yellow pole markers left in my drive way (1976 that cable was changed from overhead) to a cable (560m) the date is on the top of the tower. In keeping with their current maintenance standards, these are never replaced. Others 800m & 500m on property, no markers left, put down in 60's & some later with copper & plastic jacket.

They now use a plastic pole, with dial before you dig, so you can ring them & find out where it isn't & get it with the world best locator: The backhoe. If there is something there it will get it especially if there is nothing to say its there.

I was always concerned with the main local feeder to the exchange, lead type & it was a toss up between the slasher & disk harrows as to which one was going to get it as it was on the surface in several places, before it died.

That tower is likely active and Asbestos cement, if you want to cuddle it.
