Prime Minister Scott Morrison's press conference was interrupted this morning by a man telling him and members of the press to get off his newly reseeded grass.

Mr Morrison was in the byelection battleground electorate of Eden Monaro, spruiking the government's $688 million HomeBuilder scheme when a local resident called out to MPs and media to move off his lawn.

"Can everyone get off the grass please," he said.

"Hey guys, I've just reseeded that."

The Prime Minister apologised, instructing the press to move forward off the grass before offering the man a sheepish thumbs up and carrying on with the press conference.
