Very few people leave
Australia with insurance. It's just too expensive.
Are you able to get an extension in your visa under special circumstance, just long enough so you aren't pushed at all? Don't want to be reading about you here on CF if you
head off in less than the best of
weather windows.
I truly hope you have more than $14k invested. I can't see anything only worth that on such an extended
cruise.
Safety gear alone would be half that.
Welcome to CF by the way.
