The mutual obligation requirement in Australia might not be the best example, with at least 2 issues:

1. It's, in part, a thinly veiled program to transfer public money into the pockets of privately owned "Employment Service Providers"

2. It's offloading the "checking" to other private companies by way of requiring people to apply for a certain number of jobs. Any jobs. Maybe the same jobs you've been rejected for again and again so many times that HR recognizes your identical cover letters coming in every month.

3. Might be an extension of 1, but Employment Service Providers (private, for-profit companies) have the ability to report you to the government and get your payment cancelled for missing certain appointments, with little oversight and no repercussions for errors.
