Communications Minister Stephen Conroy has been caught napping as the Senate debated his legislation.
Senator Conroy was in the chamber listening to debate on a bill relating to the planned digital TV switchover.
He appeared to rest his eyes through much of a speech by Liberal backbencher Alan Eggleston before being roused by a second speaker.
"Sorry to disturb your slumber," Liberal Ian Macdonald said.
Senator Conroy offered no response.
