Can power run backwards through the transformers so that the power being generated in suburbs can be moved to the commercial and industrials areas during the day? If not then everyones solar roof top PV system is isolated to the particular 240v section of grid that they feed off of and into.
Were as the solar farms must be feeding into the Hign Voltage grid that can be sent to where it is needed.

I could setup a business in each suburb. Chewing up all that negative tariffed energy by a bank of incandescent bulbs burning away. A few hundred bar heaters in case its not enough.
Its almost like electric hot water heaters will make a resurgence, but be powered during peak sunlight hours instead of off-peak.
Don't laugh, they're called grid resistor banks and there have been proposals to operate them as an economic solution under various scenarios. Of course, it would be better to actually do something useful with the energy in the manner that you speak of.
With the amount of small shocks I get from wearing woolen jumpers in winter I can't help wondering if there might be some way to turn sheep into capacitors.

The kiwi's have been doing many many many hours of research into the science of friction producing energy with sheep.
Maybe we could just attach an extension lead to all the kiwi's and let the out into the paddock.

This governments policy on electric vehicles is basically a policy to STOP electric vehicles !
But before you jump all over Morrison - the labor state government in Vic wants to Tax EV's for not using petrol.
When it comes to EV's this country is 15 years behind the rest of the world.....
Without question its the lobbyists !!
All of the states will struggle with electric vehicles. They expect to see money from fuel sales, so if these levels fall they will need to make it back somewhere else.
Are the taxes proposed equivalent to what they would have gotten from fuel excise for a comparable car?

I think that's what's happening here: solar panels everywhere, and people have gone from gas water heating to electric.
When we used to be about to go home, is count the solar roofs I saw on my travels. 7 was as many as I ever saw. I can see more houses with PV without leaving the yard. And every paddy farmer seems to have a solar farm...
Some really good resources here if you are interesting in reducing your energy use. This is where the most benefit is.

Also a good explanation of how the grid works was on Catalyst the other night.

Even the grid operator AEMO says it can make renewables work, it just needs to be designed to do it.

This app is interesting and shows how the grid can share power around from where there is excess supply, to when there is demand.

Not sure the purpose is to tax for not using petrol.
The excise tax on petrol can be viewed in two factors, a) a portion to pay for the roads, b) a carbon tax.
Electric vehicle owners should pay the road tax portion, (electric cars need bridges as well as petrol cars) and if the remaining portion that can be viewed as a carbon tax is above the market value of carbon offsets, then economically, the tax on the petrol vehicles should be reduced, and vice versa.

All Australia really needs is DC Ultra High Voltage Transition Lines.
Resolve possibly every problem energy face here in Australia now and in the future.
One thick piece of copper going along whole our island.
It may works like that:
we in Australia have the greatest copper ore resources in the world
we know how to dig.
we could dig it out and send to China for processing.
All China needs is our copper ore and our coal to power smelting. We have plenty of both .
Once smelted and rolled into cable, we could bring copper line back here .
Then all we need is to hang it or dig underground!
All problems solved ! Easy!
We obviously could dig it and smelt ourselves , but it takes another century to complete design project.

Is copper what they would use? Steel? Aluminium?
Does DC have skin-effect?
It would be nice to have an interconnect between east and west, but I guess the cost would probably outweigh any advantages.

The technology isn't new. There are already several HVDC links in operation in Australia. They have been, and will continue to be, evaluated as a network augmentation option. There is nothing special about them, they are not a silver bullet. They have pros and cons like everything else, solving some problems but creating others, all at a substantial cost.

There is ! - they don't stack up financially and some developers have lost a fortune...
Too many issues to mention but most revolving around Govt red tape.
A lot of the issues are related to the developers having little understanding of the power system constraints and how they will be impacted. Often they only want to develop a project to the point where the approval can be sold to an investor. Unlike in many overseas power systems, generators in Australia have no firm transmission access rights, so there is no guarantee that they will be able to get all of their generated power onto the network. The investor buys the project, they build it, and only then do they find out that their generation suffers significant curtailment.
Surely the consultant teams should know this stuff ? I was scared off after one meeting looking into the opportunities....

Thats the tax they are looking to claw back if people move away from fossil fuels to EV's.
The irony being most forward thinking states (overseas) are giving subsidies to encourage EV car sales...

The rest of the world is giving incentives for EV uptake. Here in Aus we are applying new taxes which is a deterrent.

Some do, some don't. There is good and bad advice out there. There is limited visibility of some important data. Despite the large sums of money involved, some just seem to want to put the blinkers on and push forward in blissful ignorance. As you said yourself, some have lost a fortune.

Q>1.Is copper what they would use? Steel? Aluminium?
A.-I think the is top secret, so nobody could copy their technology. We could not just made our own UHVDC. We need to buy a patent or pay royalties for every electron sent on network.
Q>skin effect?
Ai am almost sure the touching that 1.2MV cable may have adverse effect on your skin > (haha, I know , you refer to ultra high frequency current, But in fact there is more to think about in your question!!! Indeed , high voltage should cause electrostatic repulsion ! I am not sure how it works inside conductor , needs more reading and learning 
)
Q.It would be nice to have an interconnect between east and west, but I guess the cost would probably outweigh any advantages.
A. Lets do this weight comparison then>
a) weight of copper per kg against unlimited output from all potential green energy sources: wind , tidal, solar, hydro , attached storage- available to anybody across Australia. From everybody willing to sell to everybody willing to buy and pay for it.
We no longer need to shut down aluminium processing plants because of the lacking electric power.
We don';t need to sell cheap hydrogen to Japan because we could make something worth here.
We always could send excess of energy across ocen to Singapore buyer.
All this above only possible on DC not AC network.
BUT that assurance can not come from MACRO here on SB.We need to hire highest degree expert overseas, to tell you the same in the complex language that you don't understand but trust fully.

How often would they fine you? If you sat on 120 km/h for an hour, do you get a fine every 5 minutes? And if the electronics start to play up on you car, heck, geez....have fun trying to scrape back the money.
Imagine the chaos in peak hour traffic when you can't momentarily exceed the speed limit to allow you slot into a gap between cars in the lane next to you, not to mention the dangerous overtaking situations it would produce.
It makes eminent sense for cars that are designed to go at 2 or 3 times any speed limit in the land to be fitted with a GPS device to ensure they aren't being used illegally.

No idea, I don't think it got that far. Oddly enough, I was wondering the same thing the other day...
If you exceed the speed limit when overtaking, you get a ticket. Duh. /s
Cops in NZ like to camp out at the overtaking lanes on the state "highways" and capitalize on the psychological phenomena that has the drivers who are doing 80 in the 100 zone speeding up to nearly 100 as the road widens, thereby forcing the people who've been stuck behind them for ages to exceed the limit to get past.
Here is better: there's no radar in police cars, there's few speed cameras, and unless they're feeling particularly salty, they don't ticket you at radar traps they advertise in newspapers unless you're more than 20 over the limit. Half the traffic deaths per 100,000 of NZ... Now if we could just stop people looking at their GODDAMN phones in the car.

That is what I like the most...overtaking...
I promised not to pay anymore speed tickets in my life ( not to get reason to be ticketed to be clear)
So I setup my digital cruise control to exact 100km/h
BTW. Mercedes factory possibly for extra safety made this 97km/h as I did verified with accurate GPS on many occasions.
Then if need for overtaking happen on my 300km road to farm - could be once or twice- on some extra long train tracks - whole procedure of overtaking takes 5 minutes ? 10 km . Driving side by side, huge wheels spilling the mad and stones
But I don't care... I will not get ticket anymore......
better be safe then sorry...

A dollar for every second at 10kph over. A warning bell would sound and your balance would be ticking down on your 10.5 inch monitor. You would have to watch both battery charge/petrol and credit balances to keep driving. Macro can pass that road train in half the time but it will cost him $5.
Barring that, at least can we have external display of a car's speed? Maybe a lit up band at bumper height so no confusion with emergency vehicles. 0-40kph green bar, 40-50 flashing green, 50-60 blue, 60 -70 flashing blue.....
Would peer group pressure keep us at safe speeds?
Why go to the effort of concealed radars to monitor speed when the information is all known by the motor car. And we have modern communication systems to transmit it to wherever needed.
