Government sends 140 Serco staff to Christmas Island despite no refugees being there

Serco handles security and logistics at the facility on behalf of the government. There were also 14 medical staffers on the island and a small number of extra Border Force and Federal Police officials.

Home Affairs assistant secretary Stephanie Cargill said the $185 million cost was based on the assumption up to 250 people would be detained there. Currently the population is zero. But much of the expense involved fixed costs related to the reopening.
