Predictions of a million new homeless in Australia, and zero chance of employment for them. Will this be a precursor to the UN "peace-keeper" forces?
I have no idea why the UN should act here.
Here, if there's an eviction due to the pandemic lockdown, help/remedy is regulated by various lockdown-related laws and by-laws.
Homelessness generally (and in all other cases) is regulated in the Sozialgesetzbuch (SGB)
• depending on the individual case, the rent debts can be taken over or the staff of the social welfare office can negotiate with the landlord to get you back in the flat,
• in individual cases and under certain conditions, you can receive money to help finance the costs. This financial aid is usually in the form of a loan,
• the public housing cooperatives in every municipality have always (that's the idea behind these co-ops since nearly 150 years) some spare flats just for such cases.
