"They told Emily to stay home from camp because they didn't want to upset Mitch's prep," a male source told The Daily Telegraph.
"They said it would be in her best interest to stay home or delay attending."
World backstroke champion Seebohm only joined the Dolphins on Wednesday with three days of their two week Cairns camp remaining.
Larkin attended the camp, but pulled out of the ยญCitizens of the Great Barrier Reef expedition last week โ a program supported by Swimming Australia designed to raise awareness for the health of the reef.
Seebohm has since gone public with veiled messages about the couple's separation on social media.
"I would like to take this opportunity before more speculation and rumours are spread," she wrote on her Instagram page.
"Due to current events that have occurred, Mitch Larkin and I have decided to end our relationship."
The situation has turned even messier with reports surfacing Larkin is upset that the circumstances behind their separation have been publicly reported.
Seebohm last Sunday night offered another insight into the bitterness within the breakup with a scathing dig at Larkin which included a warning about the six-time Commonwealth Games gold medallist.
She posted a photo on her Instagram story which said: "Something I learned about people... if they do it once, they'll do it again".
She then posted another cryptic warning on Twitter, interpreted by many fans as another swipe at Larkin โ and his reported anger at their breakup becoming public knowledge.
eebohm last week also posted another image of herself performing acrobatic moves around a pole dancing pole.
"This is the only bender I go on these days @purepoleacademy #purepole," Seebohm captioned the image.
She also told a fan on Instagram last Thursday: "It's been a hard month for me but I'm doing my best."
The Courier-Mail reported last week Seebohm and former backstroke competitor ยญMeagen Nay, who also previously dated Larkin, shared messages on social media.
"There is hard evidence in here, trust me," Nay posted on social media.
Nay and Seebohm also made identical posts to their Instagram stories, each posting the same image of a seascape with the quote "What is coming is better than what is gone".
Seebohm posted another image on Instagram last week with a message that appeared to be about Larkin.
"The sad thing is, I actually thought you were different," she wrote.
