Victoria says it's 'on track' to deliver 300000 vaccines by mid-May. Here's how that will work

The Victorian government has set a goal of administering 300,000 vaccines by May 16, and so far, it says things are on track. The state government has even offered to expand its vaccination program and help administer jabs to people the federal government is currently responsible for vaccinating. So how does Victoria aim to meet this goal, and what else is it offering to do?
