Foreign ownership should be restricted to citizens of countries which allow ownership for Australians in return. No ifs no buts.
Foreign aid can be structured that only goods & services are provided, no money. Indonesia could possibly come to the party if Australia said the less boats that arrive in australian territory or waters the more foreign aid will be coming their way.
Australia could actually re-stimulate a lot of manufacturing industry by using australian made products as foreign aid.
The rich in poor countries have enough wealth, they don't need any cash from us. Their poor don't need money either, they need goods that can't be stolen from them by their rich.
It really is as simple as it sounds.

individual,
It is not that long ago that we were actually supplying the Russian Army with Greatcoats because we produced the best woo and made the best material. I think the company was Onkiparinga or something like that. Now we have no wool, no mills and no market.
We are even now importing water from New Zealand.

"it is not that long ago that we were actually supplying the Russian Army with Greatcoats"
chrisgaff1000 please tell me it was not to the "Bolshwviks" not only were they about to invade us, so said Pig Iron Bob, now I find out after all these years they were going to be warm doing it. Did we ever sell rice to the Yellow Peril, please tell me its not so.
"We are even now importing water from New Zealand" and Fiji, after all we are a dry continent and some parts don't get much rain. Could tell Barry to turn on the desal plant at Kurnell, after all its costing the NSW taxpayer enough, we could buy all the water in New Zealand for the cost of it. LOL

Did we ever sell rice to the Yellow Peril,
Paul1405,
I am surprised you're still using that outdated racist term. It won't get you any mileage here.
However, some Australians have actually sold their land to Chinese instead of keeping it in australian ownership. Talk about money being king.

Dear Individual,

The government just borrowed $800 million
probably to buy back Indonesian boats.
This will undoubtedly fuel the boat-building industry
in Indonesia. - They'll be able to build more boats
and transport more people over here.

Unfortunately Foxy my sweet, our new government is going to have to borrow money for a few years, just to make the interest payments on Labors wasteful spending on the credit card.

They are going to have to drop some of Labors projected spending on NBNs, NDIS & Gonski among other things, or the borrowing to pay the interest bill will still be required when our grand kids are old & grey.
