Hearing about the Urea shortage...caused by China deciding to ban exports of the stuff to Australia (used to make Adblue and similar diesel engine anti-emission additives) it looks like long distance trucking may grind to a halt in the New Year.
The cost of all road freight may well go ballistic as a result.
Funny....we used to have these things called "Trains" that ran on steel rails to many regional towns....
P.S.
As an aside, Strategically, Australia is in a mess. Can't produce mRNA vaccines, Just two steel mills, two oil refineries and four bombs away from closing *all* of the arterial roads of its largest city.
