Only four of the 111 refugees and asylum-seekers transferred to Australia under the so-called Medevac laws have been admitted to hospital for treatment, a senate inquiry has heard.

And of those transferred since the laws came into effect in March, just 40 have received treatment as outpatients.

The details were revealed by Department of Home Affairs during the Senate inquiry into the Federal Government’s bill to repeal the Medevac bill.

“When these persons arrive, we see very low incidents of hospitalisations,” the department’s first secretary Mike Pezzullo said.
