Probably to be replaced by more efficient models. In other parts of the world they would be salvaged for parts. However, in the USA, lets blow them up for the spectacle.
You'd need either a huge crane or an industrial lift helicopter to dismantle it that way. The most valuable bits inside the turbine housing will be the 5 tonnes or so of scrap copper in each one and that's not going to be particularly compromised by slamming it into the ground.

A website which I cannot access from work laptop says some were salvaged for parts the rest demolished and scrapped.

The turbines are 20 year old 1 MW units designed for low wind speed areas, so there wouldn't be much demand for this size.

Interesting Pic of the damaged steam turbine at Callide:

Looks to me possibly the generator coupling or other coupling in the forground. Reminds me of a failure of a 500MW machine at Duhva many years ago. In that case it was an overspeed test gone wrong.

We're having an over-supply of wind energy today and the price per kw/h has gone negative. These are the moments that the proponents of wind energy trumpet - however on Friday there was a 'wind drought' during the evening peak with less than one percent of our energy coming from wind. They had to fire up the diesel generators - the very dirtiest and most expensive kind of energy generation.

Interesting to note that at the exact same time (Friday PM peak) there was a 'wind drought' all over the NEM - so the new HV inter-connector from NSW would have been equally useless if NSW was mostly 'renewable' like us here in SA. You have to wonder what will happen when coal isn't there any longer to back it up.

While extensive periods of negative or near zero prices may look great for consumers, such prices discourage further expansion but will drive expansion of storage technology investment.

Diesel gensets will always be part of the mix as they are for most grid's globally to manage extreme periods of high demand and has little to do with the main source of energy. SA has operated diesel for at least 15 years and fortunately for SA, is actually lower / MWh than Coal in CO2 emissions. Additionally a number of diesel generator plants in Australia also run additional scrubbers to remove non CO2 emissions such as NOX and SOX.

Diesel peaking capacity is expensive per MW, however this is because its treated as top peaking capacity and thus used rarely so when they do they rightfully jack the price up for CAPEX recovery.

Its worth noting at the time of SA's "wind drought",
- Vic was sharing SA's "wind drought", no real surprises there.

however
- Tas's wind was down to about 1/4 during the "wind drought", thus demonstrating geographic diversity is critical when looking at weather related energy sources.
- NSW wind was generating around 60% of nameplate
- Qld wind was operating > 60% of nameplate
[in all cases these are rough estimates of the actual % of nameplate without counting to the nearest MW]

The proposed HV connector into NSW would have tapped into NSW's existing significant hydro and SNOWY 2.0 peaking generation capacity and as it turns out NSW still had a reasonable amount of wind output, but the imported power to SA was rather sourced from Vic and Tas hydro sources. So to state the HV link would have been useless is wishful thinking.

Probably not a good idea to have gas and oil wells 5km offshore from the 12 Apostles:

Yeah, its not a good look to have a drilling rig off The GOR, but nothing wrong with looking I suppose.

The article does how ever loose credibility when they say it will be a "stranded asset in 10 years". The objectors and author will get more credibility if they focus on the impact on tourism than BS'ing about what they wish industry will do, but won't because industry lives in the real world.

Burning coal is good for the planet, plant life can't exist below about 240 ppm CO2. More CO2 will be better for plant growth and the water cycle.

It's not wrong, I've posted before about the fact that the CO2 concentration is pretty much the lowest in the history of the planet. Releasing the sequestered CO2 will not destroy the planet, it'll just return it to a slightly different balance in which life has survived before.

I really don't get the assumption that catastrophic change will result... it won't.
But did you like Brian Cadd?

Where did I say that I knew everything about everything - hysterical much?

And where is your counter-argument that increasing CO2 will cause the world to end -

Then again what you've given me there is the scripted response you get from nearly everyone who believes in the fake cult of climate change. You're convinced what you're told is true about the end of the world being immanent but you have no idea how its supposed to happen. All you know is that wind turbines and electric cars are the answer.

Keep your pants on Don, no need to be so sensitive, or 'sensibile' as our Latin friends say. I just pointed out that you are one of the few Australians who don't know Brian Cadd's biggest hit, after you yourself offensively admitted to not knowing who he is. Or do you know him, yet get some perverse pleasure in putting on an ignorant show?
