Curious if this could be a way past some tax.

I just want to throw a few scenarios out to see if anyone knows if this is possible/legal.
(ps, quite new to this so apologies if this sounds incredibly stupid)

* An off market transfer for of the shares held to a retiree (parents) where the shares are transferred as payment for food/housing over the span of ones life. Shares than put into a self managed super fund that i believe isn't taxed.

or.

* Gain residency overseas then sell (would you still be taxed in the country you bought the shares?)

Thanks.
