Isaac Heeney's ex-fiancée Steffie Waters takes a dig at AFL star's Thai massage parlour visit as she returns to their shared home in Sydney following her split with Swans player

Isaac Heeney's ex-fiancée Steffie Waters took a not so subtle dig at the Sydney Swans star when she returned to their home in Maroubra over the weekend.

Last month, Heeney was spotted leaving a Thai massage parlour in the suburb looking relaxed following a treatment.

On Sunday, Steffie shared a photo of herself walking past the same parlour.

In the photo, her posture and clothing appeared to mimic a paparazzi image taken of Heeney as he exited the same premises.

She captioned her picture with some cheeky words: 'If you know, you know.' 

Steffie appears to have returned to the estranged couple's shared home after living it up at a music festival in Texas with a friend, following her split from the AFL star over a scandal involving several Swans players and strippers at a Melbourne hotel earlier this year. 

The blonde shared several photos of herself partying with her pal Miranda Rack at the Austin City Limits Music Festival in Zilker Park, Austin. 

Meanwhile, Heeney appears to still be overseas and was last seen at the Hong Kong races during a boys' trip.

Last Wednesday, the 30-year-old appeared to be in good spirits at Happy Valley racecourse, where he cheered his horse Brownneedsfurther to victory.

Heeney was spotted at Happy Valley on the same day Steffie returned to Sydney after she fled the US in the wake of the Sydney Swans scandal.

Last month, the Daily Mail reported that Steffie had quietly called off her engagement with Heeney.

Heeney, along with teammates Chad Warner, Nick Blakey, James Jordon and Riley Bice, was stood down by the club for attending a wild party at the Pullman East Melbourne with three strippers after the Swans' August 16 victory over Essendon.

The three dancers later made police complaints alleging they had been sexually assaulted. No charges were laid and the women have engaged civil lawyers.

The Daily Mail does not suggest the players named are personally under investigation. Their suspensions related to breaches of the club's code of conduct, including drinking and bringing women back to hotel rooms, and were not connected to the police investigation.

Weeks after the fateful night, Steffie is said to have been unable to forgive what she sees as Heeney's betrayal by partying with strippers.

Within hours of the hotel scandal breaking, she fled the couple's $4 million Maroubra home and flew interstate to Noosa to avoid the media storm. 

It is understood that Heeney spent weeks trying to save their relationship and kept in regular contact with her in the hope she would come around..

But after weeks of soul-searching, friends said Steffie ultimately could not move past what she considered an act of infidelity after he partied with exotic dancers.

'She is dealing with the breakdown of her relationship that has nothing to do with the allegations [to police], only the fact that Isaac has been unfaithful [in her eyes],' a source told the Daily Mail.

According to friends, the ongoing investigation was why Steffie had been grieving the break-up away from public view. She felt unable to make a public statement about their engagement out of respect for the official process.

The Daily Mail makes no suggestion that Heeney acted unlawfully, only that she viewed his partying with strippers as a breach of trust in their relationship.

Steffie and Heeney, who had been dating for several years, became engaged while on holiday in French Polynesia last October.

On September 19, in what was understood to be her first tentative step towards moving on, Steffie deleted several of their photos together, including their engagement post.
