Looking at Keating's legacy and sticking to things I know something about, an observation about the energy industry.
On one hand reforms broke the back of what had become overly militant unions and also reigned in some rather out of control organisations running the industry. I say that as someone who's in no way opposed to unions ideologically, just in practice some did go too far and held society to ransom.
On the other hand, National Competition Policy and things relating to it are a very real obstacle to efficient operation of the power system today. It's directly adding financial costs, fuel consumption and emissions simply because we've got different generators competing with each other when it would be more efficient if they complemented each other. End result is it's part of the cause of the present energy crisis in the eastern states simply because infrastructure that's already built, which is sitting there right now, isn't being used to its full potential due to all manner of legal and regulatory constraints that nobody dares breach.
Suffice to say it frustrates those on the technical sides that their hands are tied and that common sense cannot simply be followed to prevent silly outcomes.
In general I'd say Keating had reasonable ideas but failed to accept that not all ideas which seem reasonable in theory are actually good in practice. In anything from art to engineering, there's things which seem good until you head down the track of trying to do them and realise that actually no, they're not worth going any further with since there's actually a fatal flaw.
Within the energy industry the good thing was it stopped over building and it stopped militancy. Both were very definite problems.
The bad thing is it also stopped efficient dispatch of generating plant and it stopped effective planning for the future, both as a direct consequence of having no single entity with effective control. The chickens have now come home to roost there - Keating-era reforms certainly aren't the only cause but they're a factor.
