Subject: About the distribution of precolumbian human populations.

I'm not sure this question should be under evolution, but I was wondering about 
The distribution of precolumbian humans.  People were already in Australia, the 
Americas and even such unlikely places as Hawaii and Greenland. I'm sure there 
are islands through the world that didn't have early humans but can anyone tell 
me what the largest land masses without early humans were (other than 
Antartica)?
I appreciate your time and value your answers
