The flood of migrant workers that has helped sustain the long economic boom has all but dried up following the COVID-19-induced closure of Australia's borders.

Migrant numbers are expected to drop by 30% this financial year, and by 85% in 2020-21 (compared with 2018-19).

With the economy officially in reverse and the ranks of the unemployed and underemployed swelling, there are some who say the migration slump is no bad thing.
