For me the most important information in that statement is this:
>Mr Frydenberg said Australia's intelligence and law enforcement agencies were working closely with the private sector to protect against attacks.
It's about someone making money in the private sector and because
>I won't go into the details
there is neither credibility nor any actual information. It's a person with private/personal interestes making statements without backing them up.
That is how the INT sector operates here in Germany and since we've been copying (poorly) what US INT has been doing since the realy 80s, I'd say the lesson applies to AUS INT just as well.
>Is there any possible exaplanation, that this comment is factually correct?
I have no clue about the power grids outside of europe; keep that in mind please for the following...
Our power grid has fail safes on several layers, the best know is the multiplicity of connections: No single plant is connected to fewer than two other plants via the grid and no node in the grid can be cut off by severing less than three lines.
So any attack that would have an effect on even a single customer has to shut down more than two power plants and
cut multiple physical power lines.
I find it hard to imagine any sort of attack that accomplishes that while at the same time being preventable "just in time".
>Do power companies have some sort of intrusion detection system? Are they scanning incoming and outcoming IPs? Did they realise that there is an open connection to a Chinese IP through the MSSQL port? Did they shut down their internet connection to investigate?
>Power plants should not be connected to the internet. Ever. At all. We don't do that in Europe, the US isn't doing that afair and I sure hope Australia isn't doing that.
Critical infrastructure such as the power grid has separate communication networks... at least that's what I learned at uni and I honestly hope it's true.

If this was about a german politician I would now try to find out which family members of this guy are chairmen of which companies in the military-industrial sector. Outside of Germany this might be more subtle, maybe just stakeholders rather than chairmen.
