October 22 marks the 60th birthday of Launceston's long-time larrikin weatherman, an occasion shared by friends and former colleagues Rosalie Saville and Deborah Evans.

The trio all worked together at Southern Cross - Murphy reading the weather, Mrs Saville in sales and Mrs Evans in production.

They first discovered the strange coincidence at a birthday morning tea.

"We had to buy the party pies, cakes and slices. Suddenly on October 22 there was a big pile of food, and we worked out we all had our birthday that day," Murphy said.

"I don't think we realised on the first time that it was the same year as well."

"It was mentioned on the weather one night that it was Murph's birthday and it was when Jo said happy birthday it was the same day, and that we were the same day," Mrs Saville added.

"Then we tried to convince Murph that we needed to lie about our age."

"Because we all worked together we were all often in the same places together, people would ask Rosie and Deb how old they were and they'd say 42, so I'd say that means I was 42 as well," Murphy said.

"Not sure how old we all were... but we definitely weren't 42!

"Now that it's 60 - I suppose that we have to own up to it.

"It was really interesting, one workplace with 50 or 60 people working there at the time, all through the years at school there wasn't someone with the same birthdate as me."

"It was the same for each of us, and then suddenly there we were in the same place," Mrs Evans added.

Murphy, Mrs Evans and Mrs Saville were all meant to be overseas celebrating the occasion, but COVID-19 cancelled their travel plans.

"Instead, I'm heading to Bicheno and spending a couple of days, which will be lovely," Mrs Evans said.

"Rosalie is heading to Hobart, and Murph will be here celebrating with family.

"I was meant to be cruising the Mediterranean," Mrs Saville said.

"But instead, I'll be cruising on the Derwent with a group of girlfriends."

Murphy described marking his 60th birthday as a game of football.

"The female life expectancy is about four or five years longer than a male, so if my life was a football game I've hit three-quarter time," he said.

"I've got to do something in the next quarter to make it count."

And, when asked what that would look like, he answered:

"I've got no idea yet, I guess I'll have to Google it."
