Huntsman spider

I have an Amazon Show in my office. I walked in to the room this evening and found this giant Huntsman sitting on the screen. No doubt he thought it may be a window and that some food may be around.  

I left him in peace and he had moved on this morning. Huntsman spiders do not build webs, but hunt and forage for food. Their diet consists primarily of insects and other invertebrates, and occasionally small skinks. They are not terribly dangerous if left alone and not threatened. He has appeared in the house off and on over the last 3 weeks.
