Please consider this as a hypothetical situation. I have no plans
as yet, only some ideas.
I am retired and of retirement age (and then some).
I do not plan to retire to Bali ...yet.
However I would like to lease land and build.
(The way I plan to do this, is probably worthy of a further post,
and may cause some raised eyebrows.) However that's for later.
It's my intention to live part time on Bali, part time in Australia.
Perhaps 50/50
What might be the best visa to go for ?
