Move to OZ Help. (Or "Can't survive France" ;-) )

Hello Everyone.

I am seriously considering a position in OZ.

I intensively searched VISA information through the web and contacted agents.

Now I am looking for serious first hand experience.

Did some of you moved to OZ using a 457, or an ENS S/121?

I would tend to go with the ENS as I could stay longer but again am not aware if this long term visa lowers my chance to get the visa compared to a 457 (2 to 4 years working Visa that could lead to a 121)

Anyway, first hand experience very appreciated.

Looking forward to read you all, via PM if needed.
