Seasonal workers influx

THE concerns about an influx of seasonal workers could be allayed if the Tasmanian government introduced mandatory testing for every arrival. Get tested, be quarantined while waiting for the result (from a few hours to overnight) and if negative be released with a directive to be re-tested in 10 days. Anyone refusing a test gets told to quarantine for 14 days or leave. I do not understand why this regime is already not in place.
