Peter Overton loves nothing more than seeing the close bond between his own father John and daughters Allegra and Giselle.
"My dad's nearly 87, and he and Mum still live in the family home I grew up in," Overton, 58, tells 9honey.
"They love all their grandchildren, but Allegra and Giselle are the youngest of their grandchildren and they talk to them every day."

The Nine News Sydney presenter says this Father's Day is particularly significant to them all, as they haven't seen each other "for a while."
"We're going to buy barbecue chickens and salad and go over and sit with them, because he's been an amazing mentor and friend and dad to me," he says.
"He's an extraordinary, extraordinary human."
Overton says he hopes his daughters hold him in similar regard.

"I hope my girls see that in me and I'm sure they do, because I'm very hands-on as a dad in terms of open communication, encouraging them to always talk to us about anything," he shares.
He and wife Jessica Rowe, 54, ensure both Allegra, 17, and Giselle, 15, know they can "tell us anything and we won't judge you, but we'll try and help you navigate it."
He recalls his father, who worked as a professor of paediatric anesthesia for 40 years, being a "great communicator."
"As teenagers, we'd be traipsing down the backyard at three in the morning from a big night out, and he'd be walking up to his car and we go, 'Where you going, Dad?'" he says.
"He'd say, 'There's a big road accident coming in from Dubbo' or somewhere, 'and I'm going, the helicopter's bringing in some pretty sick kids.'
"We always admired his devotion to us but devotion to other kids and making them better. He had such a busy job but he never took his eye off us."
Overton recalls his father coming home to help them with their homework, adding, "He is the most magnificent human."
The father-of-two is similarly devoted to his daughters.
He's teaching his eldest how to drive; she's got "about 50 hours" down.
"I've ripped out the grab handles in the car from stress," Overton says.

"I was beside a learner driver the other day and I could see the father doing exactly what I do. But you know, it's all part of the passage in life, isn't it?"
There's an gradual letting go as children navigate their teenage years, a stepping back as they make their own choices and sometimes mistakes.
"I think that's being invested in them and being around and being able to listen and wanting to listen and wanting to help them but also wanting them to have their freedom as well," he says.

"Even though if you might have butterflies in your tummy, but you've got to let them fly, don't you?
"It's just finding that balance, and I think Jessica and I found that balance."
Still, there's a long road ahead as they support their daughters through Year 11 and Year 9, "navigating school and the playground relationships."
"When they come home and it hasn't been a great day, you've got to reassure them that tomorrow will be a good day, but you're allowed to feel like this," he says.
Overton says his daughters call him "Dad" unless they want something, in which case they may call him "Dada."
While the close-knit family has made too many special memories together to count, the one that stands out above all of them is the day each of his daughters were born.
"I can remember both of them vividly," he says.
"I remember Allegra just when I helped deliver her. I put my pinkies under her armpits and I went, 'It's a girl!'"
Giselle was born via emergency caesarean and he held her skin-to-skin while Rowe was tended to.
"I remember that moment, sitting there with this brand new baby and my shirt, her off just lying on my chest. They're your best memories by a million."
When it comes to giving advice to new dads this Father's Day, Overton says to "rely on your instincts."
