The 28-year-old shared a meme to Instagram on Sunday that read: 'Happiness is seeing your ex with someone uglier than you'.
Last week Daily Mail Australia revealed photos of Dan, 35 and Vanessa, 24 canoodling on a boat in Queensland.
Rhyce and Vanessa are believed to have split in March after she alleged that the controversial reality star assaulted her at a fitness camp in Thailand.
As previously reported, Vanessa cut the trip short and headed back to Australia to file for an intervention order.
Under the Victorian intervention order, which is similar to an apprehended violence order (AVO), the Perth-based carpenter is banned from contacting Vanessa.
Rhyce appeared to deny the allegations in a lengthy Instagram post back in April.
'There's always two sides to every story, and everyone needs to believe that,' he said.
'Everyone's jumped on the bandwagon without even hearing my side of the story - which I understand - if a girl makes an allegation about a claim [sic], whether it's an attractive girl or any girl, everyone's going to jump on the bandwagon, and I fully understand that.'
