News in 5: Husband's plea to missing VIC mum; 'No' campaign's legal concerns; Trump dodges gun talk.

1. “We just want her to come home”: Husband of missing Victorian mother Elisa Curry makes public plea.

The search for a Melbourne mum who disappeared from a small seaside town has ended after a third day with no sign of the woman, while her husband has pleaded for her safe return.

Elisa Curry, 42, went missing at the weekend from Aireys Inlet, a small town on the Great Ocean Road, and widespread land and air searches have failed to find her.

It was initially believed the mum-of-three went for a run with her dog at 10.30pm on Saturday, but that is now unclear, police say.

Husband David Curry begged for her and anyone with information on her whereabouts to come forward.

"I and my kids, we just want her to come home. Elisa if you're out there can you please contact us?" Mr Curry told reporters on Tuesday, AAP reports. "If anyone has seen anything or heard anything, can you please, please call police, please call triple-zero."

The family dog, a black labrador, which was believed to have been seen with Ms Curry was found on Monday.

Inspector Peter Seel said the police were treating this as a missing person's case but were not ruling out foul play.

"We are looking into all avenues," he said.

Police and family members say Ms Curry's disappearance is out of character.

She is described as Caucasian, about 167cm tall, with an athletic build, brown eyes and brown shoulder-length hair. It is not known what she was wearing at the time of her disappearance.

The area where Ms Curry was last seen is near sheer cliff faces that lead to beaches, some of which are not accessible by land, with water police searching waters off the south west cost.

The search will continue on Wednesday. Anyone with information is urged to call Triple Zero.

2. 'No' campaign faces defamation allegations.

The Coalition for Marriage is facing a potential defamation lawsuit, accused of unfairly labelling a Canberra public servant and same-sex marriage supporter as an "extremist" on its website.

A photograph of Jill Moran at what she claims was a peaceful rally appeared on the same-sex marriage opponents' website last month.

The accompanying media release hit out at the "extremists" of the Yes campaign - Moran's lawyers say it also contained allegations of violent protesting, bullying and intimidation.

The 26-year-old said she felt "sick to her stomach" when a friend pointed out how the image had been used.

"I am a passionate supporter of marriage equality and I am proud to campaign publicly, but it is completely untrue and hurtful to paint me as violent or a political extremist," Moran said in a statement on Tuesday, AAP reports.

"I am embarrassed and angry to be associated with anything other than peaceful campaigning."

But the Coalition for Marriage denies it has defamed anyone and says it was fighting for freedom of speech.

"That includes freedom of political communication," a spokeswoman told AAP in a statement, before claiming the image showed Yes campaigners "brazenly disrupting a peaceful anti-Safe Schools event in Canberra".

Slater and Gordon defamation lawyer Phil Johnston said the photograph remained online despite requests for it to be taken down and an apology issued.

Under defamation law, the Coalition for Marriage has 28 days to adhere to Slater and Gordon's requests, which were issued on September 25.

3. Trump promises to "discuss gun laws as time goes by"... just not right now.

President Donald Trump says the gunman behind the mass shooting in Las Vegas was "a very, very sick individual" but declined to call the largest mass killing in US history an act of domestic terrorism.

"We'll be talking about gun laws as times goes by," Trump told reporters at the White House on Tuesday.

Asked if the shooting was an act of domestic terrorism, he added: "He was a sick man, a demented man. Lot of problems, I guess, and we're looking into him very, very seriously."

The Sunday night shooting spree from a 32nd-floor window of the Mandalay Bay hotel is the deadliest mass shooting in modern US history, leaving at least 59 dead and another 527 injured.

The bloodshed ended after police closed in on the gunman, who shot and wounded a hotel security officer through the door of his two-room suite and then killed himself before police entered. Police said 23 guns were found in his suite, along with more than 10 suitcases.

Stephen Paddock, 64, left no immediate hint of his motive for the arsenal of high-powered weaponry he amassed, including additional guns found at his home (34 in total), or the carnage he inflicted on a crowd of 22,000 attending an outdoor country music festival.

Paddock was not known to have served in the military, or to have suffered from a history of mental illness or to have registered any social disaffection, political discontent or radical views on social media.

US officials also discounted a claim of responsibility by the militant Islamic State group.

Paddock shared his house with reported Australian girlfriend Marilou Danley, who is currently abroad. Authorities want to speak to her upon her return to the US.

4. How a complete stranger became Renee Cesario's hero in the Las Vegas shooting.

Renee Cesario was watching country singer Jason Aldean perform at the Route 91 Harvest festival when she heard loud noises that “sounded like fireworks”.

The sounds were coming from the 32nd floor of the nearby Mandalay Bay hotel, where a 64-year-old man was opening fire on the crowd.

Before she had time to digest what was happening, a man she had met just two hours before, Brendan Kelly, tackled her to the ground.

"[He] covered me from the fire," she said in a Facebook post, which was shared on the Love What Matters Facebook page.

"He looked around to see what was happening and then [the shots] just kept going. He looked at me and said 'We have to get out of here. We can't stay here. It's not safe'.

"Then he pulled my arm up to get me out of the piles of people. We had no idea who was dead or who was alive. We just started to run.

"He kept telling me it was going to be okay and to keep running until we were safe...The whole night he didn't leave my side."

The wife of Playboy founder Hugh Hefner, Crystal Hefner, said she's "heartbroken and still in disbelief" following the death of the 91-year-old last Wednesday.

In her first interview since her husband died, the 31-year-old Crystal told People there will never be another man like Hugh Hefner.

"He was an American hero. A pioneer," Crystal told the publication.

"A kind and humble soul who opened up his life and home to the world. I felt how much he loved me. I loved him so much. I am so grateful."

"He changed my life, he saved my life. He made me feel loved every single day. He was a beacon to the world, a force unlike anything else. There never has and never will be another Hugh M. Hefner.”

Hefner's funeral was held on Saturday in Los Angeles where he was laid to rest next to Marilyn Monroe.

He and Crystal - a former 'Bunny' herself - met in 2009 and were married in December, 2012.

6. Morning sickness is a problem for men, too. Yes, really.

Morning sickness is not only debilitating for many pregnant women, but can also make expectant dads more anxious, researchers have found.

A survey of 300 Australian dads-to-be showed anxiety levels were significantly higher among those whose partners battled moderate morning sickness, or the more severe hyperemesis gravidarum, which the Duchess of Cornwall Catherine Middleton is again being treated for ahead of the birth of her third child.

Lead researcher Julie Sartori said the findings suggested many dads may benefit from increased support from health professionals during pregnancy, particularly those expecting their first baby.

"Professionals would normally focus on the wellbeing of pregnant women, however, engaging the father as well may help relieve reported anxiety and improve outcomes in the long term," she said on Tuesday as the study was published in the Journal of Psychosomatic Obstetrics & Gynecology.

Nausea and vomiting occurs in 70 to 90 per cent of pregnancies, with hyperemesis gravidarum affecting about three per cent of women.

The researchers said while health professionals help women cope with morning sickness, there was little data about the impact it has on fathers.
