Out of the eight couples who have starred on The Bachelor and The Bachelorette Australia in the past five years, just half of them are still an item, but the show's affable host Osher Gunsberg says that there's more to it than love.

"We work so hard on helping them find love and while some of them might not remain together, when they leave us they have changed for the better," Gunsberg told Fairfax Media.

"I saw that change happening with Sophie [Monk]. She sticks up for herself now, she never used to do that. I try and focus on the benefit we brought to their lives."

He remained tight-lipped about the upcoming spin-off The Bachelor in Paradise, which stars old favourites including Laurina Fleure, Michael Turnbull, Leah Costa, Jarrod Woodgate and Keira Maguire – although everyone and their mother knows that the latter two are now an item.

"All I can tell you is all of the things that you loved about the characters in previous seasons are even better in paradise," he said.

Gunsberg headed back to school this week to deliver a truckload of Yoobi school supplies to children in need in South Sydney.

"There are 1.1 million children and young people in Australia living in poverty," he said.

"We have heard stories of kids sharing a pen to do their homework. Can you imagine how easy it is to fall behind when they don't even have the proper tools they need?

"Every item you buy Yoobi will give stationery to a child in need. I'm super proud to play a small part in the great work that they do."
