That will be interesting one.

it's not only that halted immigration will have huge impact on construction industry. But some half a million people will leave Australia (some estimates are up to 700-800,000) which will be devastating blow on construction, consumer spending, rentsl and real estate.

I think there will certainly be a lot of people losing their investment properties, but I think gov will step in to save as many homeowners as possible from margin calls and falling behind on payments, when property prices/rents nosedive.

It will probably be toughest for construction industry tradies. High number of those in industry are also landlords (as a substitute for superanuation). They'll have a triple hammer blow of work volume plummeting, property prices going down and high rent vacancy rate/low rents (compared to investment loans).
It certainly looks that area will have it's own lithium oversupply moment
