So how is what the government has announced compared to One Nation's offering announced earlier this week, which was based on cutting our temporary migration intake by 750,000 over three years, taking us into ne- negative migration? How does this compare to that?

Well, it's a much, uh, slower winding back of migration.

And, and it's an open question as to whether it's enough to reach the government's targets.

I think it will be, because numbers have been trending down already, and the government's done a lot of other things to slow migration.

For example, it's, um, increased the price of most visas by 25%.

It's required students to have a lot more savings than they used to have if they want to come and study in Australia.

It's increased English language requirements for various things.

Still to come, is migration or politics at the heart of this announcement? Peter, how much of this immigration issue is about politics and One Nation putting it on the agenda, and how much is it, of it is a, a real problem with our migration levels, or is it both?

Lip-stitching.

The lip-stitching protest at the Curtin Air Base, which was another detention centre in the far north of WA, was essentially a hunger strike, a form of hunger strike, but it was also about being silenced, about people not being able to speak, not being heard, not being able to speak, not being able to say what was going on for them.

People also dug graves and lay in them in the dirt.

And it was very hard to get news of these things.

You'd only get news sort of secondhand mostly because no one was allowed into the detention centres, no independent people, maybe some lawyers and some social workers and things.

But it was very hard to get information, accurate information about what was going on.

We discussed his efforts to find out what was going on inside.

Well, Woomera, as people may know, was originally a military base essentially for rocket testing in the far north of South Australia.

solve the problems that your report has identified

for the workers? Well, I think the big problem that the workers have, the biggest problem, is that they're tied to their employer.

So your visa under Palm is a visa to work for one particular employer.

Now, if you are having problems, you're being exploited at work or abused or the accommodation's terrible or you think your deductions aren't right, The first thing you should do, of course, is talk to your welfare officer or talk to your employer.

But many workers are reluctant to do that for a range of reasons, cultural reasons sometimes, you know, questioning authority.

But also they know that this employer basically has the right to send them home or to say, well, you're not coming back again next time if it's a seasonal visa.

We don't want you back next year because you've complained too much.

Why have those employers been given this extraordinary power over their workers?
