Bert and Patti Newton are said to be the legendary golden couple of Australian television. As the pair have been married for almost 46 years, Patti, 75 has revealed the secret to her long-lasting marriage to Bert, 82.

The couple first met as child radio stars before working together at Channel 7 and stayed in contact throughout their teens before a fateful night at Patti's 21st had Bert realising she was the one.

"I was working on the QE11 in 1974 43 years ago. Bert surprised me and got on board and asked me to marry him. A wonderful Australia Day and the best thing I ever did xx," she penned on Instagram in 2017.

Two children and six grandchildren later, she told Now To Love that she would be lost without her husband.

"We lived and worked everything that was happening on television, we've spent a lot of time together. If anything happens to either of us, whichever one it is will find it very difficult because we've been in one another's pockets for well over 50 years," Patti says.

She's admitted that having a good sense of humour helps a marriage.

"I think you have to have a good sense of humour, that's something I do have, I'm always ribbing him about something. I know that he doesn't do the dishwasher very well, but the reason I know that is because if he did do it well, I'd ask him to do it more," Patti laughs.

However, the importance of time apart can't be underestimated.

"You have to give one another a bit of space, we both have different interests," she explains.

"Because we give one another space, and we're both very loyal to one another, it worked out very well."

"I look after him and he looks after me, that's what it is really all about."
