As new variants spread across the globe, it's more important than ever that we are constantly refining, adapting, and tightening our border and our approach. This year, we began pre-departure testing, we mandated mask use across the country on public transport, we introduced day zero testing for those arriving in the country, we limited more movement in our managed isolation facilities, and we've been upgrading ventilation systems, to name just a few of the improvements that have been made this year alone. We want our systems to keep changing and improving as our knowledge base continues to grow.
