Marles continues breakfast rounds to discuss defence spending

The defence minister, Richard Marles, has been making the rounds this morning and has also spoken to ABC RN about yesterday's defence announcement.

The reason why we make the observation that an invasion of Australia is a very unlikely scenario, no matter what happens, is because any adversary that wished to do us harm could do so much to us before ever setting foot on Australian soil - and disrupting those specific sea lines of communication, which I've described, would obviously achieve that. That that is where the risk of coercion lies, as one example.

And in order to protect ourselves in respect of that, we do need the ability to [project], because if you think about it, ... the geography of our national security when seen through those lands is not the coastline of our continent. It in fact, lies much further afield.

We're looking at a substantial increase on what's already in the Online Safety Act. So not only a large amount - so for example, a $3m fine for an offence and ongoing fines, but a percentage of turnover as well.

We know that the revenues of some of these online platforms exceed those of some nations and so it needs to be a meaningful and substantial penalty system that's put in place.
