ttbn,
Here’s another chance for you to shew us all how you would handle the situation.
What’s your solution to the double handling problem and consequent delays and the lack of suitable ports?
Not all the NSW ports, such as they are, have a rail line to them; there’s more infrastructure needed.

Get a life.

ttbn,
You can do better than that, shew us all the solution, surely you have one; we might disagree with it but we won’t laugh.

shew us all how you would handle the situation.
Is Mise,
Start with freezing Public Service salaries & deduct a 1% infrastructure levy from everyone.
Impose a Public Service salary ceiling of 500,000/year.
Start a Gap year National Service for all unemployed aged 18-21.
That'd be a good start to start building infrastructure for continued employment.

individual,
Big order; there are only 5 deep water ports on the NSW coast and four of them are in the 185 kms between Newcastle and Wollongong plus Jervis Bay well south.
The rest of the ‘Ports’, so called, are mainly rivers and can only take small ships.

I had experience of visiting NSW ports in a square rigger that only drew 10 fett and we were very restricted as to which ports we could safely enter.

Dredging ports isn’t going to make many jobs as the same couple of dredges could move from port to port or, if the company that won the contracts, kept dreadges in each port, then there need only be a couple of crews who’d move to each new job..

Anyway you look at it coastal shipping has a very limited future.

No amount of wage saving and cost cutting will do away with the lost time caused by double handling.
For example, a machine that could be carried on a truck , 2 kilometres from the factory to the wharf, could be in Melbourne, by the truck before the ship cleared port

Is Mise,
One of hurdles with Australian infrastructure deficiency is the deficient infrastructure thinking. If natural conditions are not suitable, make them suitable. No need to ruin the environment, enhance it.
If shipping is not a viable option make it rail because long haulage trucking is also not viable.
Create infrastructure not wait for it to magically appear to enable economic & social stability.
Aim to provide for all the community not just please a few useless megalomaniacs !
Engage people to make them appreciate what they get for what they put in an effort !
Most of all, move away from that insane entitlement mentality !
