Why Are Aussies So Hated?

Reading the article it is managed by an "electronic system", i.e. the swipe card is the authentication.

The second you had to hire a human being to attend the cage is the second it becomes untenable from a financial perspective.

I like the idea but it does create a false expectation regarding security- and that's never a good thing.

It's not necessary to have a person only dedicated to monitoring the cages. It could be built into the work of other station staff (if indeed there still are station staff ...).
