He was refused bail and is expected to appear before Lismore Local Court today.
Yesterday, Assistant Police Commissioner Peter McKenna said the man was alone inside the property throughout the siege.
“At no time did that person of interest leave that property,” McKenna said.
“One of the precautions was to evacuate local areas just around that exclusion zone and that was all that was about.”
