The federal budget, to be delivered by Frydenberg on Tuesday, will include core assumptions for coronavirus vaccinations and infections to aim for the opening of the international border in 2022, several months after the forecast in the budget seven months ago. “The borders will reopen when it’s safe to do so, and when they do, net overseas migration will increase, including skilled workers,” Frydenberg told The Sydney Morning Herald and The Age. “And those skilled workers play a very important role across the economy, but we’re not going to compromise public safety, or indeed the economic recovery, by moving ahead of the medical advice.”
