Yes.
Political campaign contributions is the perfect euphemism for corruption.
Corporations aren't allowed to make direct campaign contributions in Norway; political campaigns are paid for by the public.
(I've been an expat for over two decades, please correct me if anything has significantly changed - of course the companies still have political influence through choices of where to invest etc, but at least it's nowhere as blatant).
One might say it would be a waste of taxpayer money to do the same in Australia, but in the end we would be far better off by cutting off the direct corporate influence.
We might not have gotten an EV tax instead of incentives if we had politicians not directly receiving money from big petrol.
And we might just be able to raise corporate mining taxes to a far better level, clearly state that if you don't like it then just pack up and leave - and let someone else who is willing come profit instead.
