The travel advice is a bit redundant now that we’ve really clamped down on international travel. But there’s probably no risk from local travel, domestically, as long as you try and avoid crowds. And that’s the problem, you’re in an airport, you’re in a plane, and the more that you come in contact with other people, the more likely you are to get the virus. But, because roughly the infection rate is about the same across Australia, maybe a bit more in New South Wales and other states, interstate travel is probably okay. But, you’ve really got to be careful.
