Mr Morrison said he was more concerned for those attending the conference than his own personal safety in the bid to replicate the recent egging incident involving Senator Fraser Anning.

"I just thought it was very irresponsible," he said.

"It was just a very careless thing for someone to do, I just don't understand why people don't think of the impact on others.

"Whether it is protests on farms or storming peoples' homes and things like this.

"It's like they think because they have a particular political view about something it justifies any sort of behaviour whatsoever.

"It was a roomful in many cases some older ladies and I just thought it was a reckless and careless thing to do.It showed a lack of respect."

Mr Morrison attended the CWA conference with his wife Jenny and had earlier spoken about laws his government plans to introduce if re-elected after the May 18 federal poll to prevent vegan activists targeting farmers' properties.

"We've had people basically storming farms from ignorance, a position of intolerance, from a lack of understanding and appreciation," he said.

"I won't stand for that.

"One of the first bills to be put in the parliament if re-elected is the bill that will criminalise that activity that is inciting that level of violence and invasion of peoples' properties.

"We will do in the first week we are elected."

Mr Morrison also pledged to eliminate mobile phone blackspots across one million square kilometres by 2025.

"It is an area larger than the size of South Australia," he said.
