Canada and Australia, obviously, have different compliance regimes.

The expectations from the Home Office for Level 4 Visas are quite well documented and have very specific conditions that education providers must show to satisfy, e.g. the students who hold these Visas attend all their classes. A provider (University) can have their ability to sponsor Visas removed if their compliance isn't adequate.

Part of the reasons Universities in the UK record attendance at all is because of the compliance regime from the Home Office. The story therefore is that these universities are inadequately complying.
