Lyon and Ms Waring broke up in 2017 when he started dating Emma McCarthy

Australian cricketer Nathan Lyon is still trying to sell the waterfront mansion he shared with ex-parter Mel Waring before leaving her for blonde beauty Emma McCarthy.

This is the second time the spin-bowler has tried to offload the Port Hacking home in Sydney's Sutherland Shire, after a prospective buyer changed their mind.

Lyon had sold the four-bedroom, four-bathroom mansion for about $3.85million before he jetted overseas for the Cricket World Cup in May, realestate.com.au reported.

But the sale fell at through and Lyon was forced to put the idyllic pad on the market again.

The 31-year-old cricket star could pocket even more cash, according to the $3.8 million to $4.2 million price guide.

Lyon bought the home for $3.8million in 2016 while living with the mother of his two daughters, Ms Waring.

The couple broke up about one-year later when Lyon began dating Ms McCarthy.

Lyon's decade-long relationship with Ms Waring came crashing down when he was photographed passionately kissing Ms McCarthy in Perth, at the end of 2017.

Ms Waring said at the time she was left 'devastated' by seeing photos of her partner of ten years with the glamorous blonde.

Ms Waring later spoke candidly about her struggles to cope with the relationship breakdown in a series of posts on her blog, Life of Lyons.

'We have lived a life where he has constantly travelled, cricket was life and touring was a given... it's easy to forget,' she wrote in March 2018.

'Today has been different. I have been strong, I have been brave, but today I feel weak, I feel small and I feel alone.'

Lyon's new relationship has appeared to go from strength-to-strength, with Ms McCarthy heading on lavish overseas holidays with the cricketer and joining the bowler in England for the World Cup and the Ashes.

Speaking to cricket.com.au after the Ashes, Lyon revealed Ms McCarthy helped him forget about a horrendous error that cost Australia the third Test and the series win.

Lyon fumbled the ball and missed a golden opportunity to run out Jack Leach at Headingley.

'I was lucky enough to have Emma with me to help take my mind off things, and some family was there as well,' Lyon said.

'It was just easy to talk to those guys and Em and make sure I could forget about Headingley as quick as I could.'
