Brittany Higgins and David Sharaz announce their engagement

Sharaz proposed at the Bryon Bay lighthouse, sharing a selection of photographs on Instagram of the special moment.

"I didn't want to enter another year without you knowing that I want to spend all my years with you ... I'm the luckiest guy in the world," Sharaz said.

Higgins posted her message, "So lucky to be spending a lifetime with you @davidsharaz."

The photographs show Sharaz proposing on one knee. "I'm just a guy, kneeling in front of a girl, asking her to marry him," he said on Instagram.

Other photographs show a staircase decorated with candles and rose petals and scenic shots of the lighthouse. On Higgins' account, there's a close up of the six-claw solitaire diamond ring.

The pair were inundated with messages from well-wishers.

Grace Tame said, "Can't think of a more deserving pair of humans. Love you two. Big hugs and congratulations. What a way to bring in 2023."
