Which is better: UK, Australia or New Zealand student visa?

Hi!

There's a lot of buzz with this new scheme of sending out nurses to "study and work" in UK, Australia and New Zealand through student visas. But there are clouds of doubt with regards to the 'real working conditions" in those said countries are what those visa placement agencies claim them to be.

I was enticed by the program for UK. It was even on the news last night (ABS-CBN). I was skeptical since they accept even undergrads, Practical Nurses and midwives. So, if i really work there (UK) as RN, why in the world would they accept undergrads?!

A quick look over at some internet forum sites opened my eyes. In UK, going there though these student visa scheme, you wouldn't work there as a nurse, but rather as a caregiver (with paid working hours up to 20 hours/week, as this is a requirement of the course). AND with NO GUARANTEE of staying there (or even getting a permit to work) after the entire duration of the course is over.

So my question is this: Is the Australia and New Zealand student visa schemes similar to UK?

If not, how do they differ?
If yes, which is better?

I would like to solicit the advice of those Filipino nurses who are already in the UK, Australia and NZ.

An informative reply would be very much appreaciated.
