A private investigator in Australia has outlined what she describes as the "ultimate cheater profile," detailing traits and occupations that she has observed to be more frequently associated with infidelity. Cassie Crofts, who operates Venus Investigations, stated that infidelity is not limited to any specific demographic but often involves individuals who have the opportunity due to their work, lifestyle, or social standing, coupled with a sense of entitlement or a belief they can avoid detection.

Crofts noted that a significant factor can be a person's commitment level in a long-term relationship. She indicated that some individuals may experience increased anxiety and a propensity to cheat when nearing milestones such as engagement. She also observed that many individuals involved in infidelity have been in relationships for extended periods where their partner has expressed a desire for progression, such as marriage or starting a family, but this has not materialized.

According to Crofts' experience, certain professions are more likely to present opportunities for infidelity. These include roles in FIFO (Fly-In, Fly-Out) work, healthcare, hospitality, sales, and senior executive positions. The commonalities among these jobs often involve irregular work hours, frequent travel, and a lack of direct oversight regarding how time is spent.

For men, Crofts suggested that those in relationships where their partners are stay-at-home mothers or work part-time may exhibit a history of blurred boundaries, such as being overly flirtatious. Unfaithful women, she observed, often exhibit a high need for external validation, feeling "chosen" through in-person interactions or social media. These individuals may frequently pursue new activities, jobs, or hobbies, a pattern that can extend into their relationships.

Most individuals Crofts investigates are in their late 30s, 40s, and 50s. She attributes this demographic trend partly to the cost of her services, suggesting that younger individuals may be less invested in long-term relationships and more inclined to leave without concrete proof of infidelity. She also speculates that younger people might utilize technology for their own investigations rather than hiring a private investigator.

Specific occupations identified as having a higher likelihood of infidelity include:

  • FIFO workers: Extended periods away from home with limited activities can contribute to infidelity.
  • Healthcare professionals: Long hours and shift work are cited as common factors.
  • Hospitality staff: Late nights, alcohol, and demanding work schedules can lead to slip-ups.
  • Sales representatives: Frequent travel for "client meetings," opportunities for socializing, and a confident demeanor are noted.
  • Senior executives: Limited oversight from superiors can provide opportunities for infidelity.

Crofts also pointed to subtle behavioral changes that might indicate infidelity. These can include a partner becoming more secretive with their phone, increased use of cash, adopting new hobbies with reluctance to involve their partner, or a history of disregarding relationship boundaries. A decline in interest in the partner's daily life and avoidance of serious conversations about long-term plans or joint commitments can also be signs.

She noted that technology plays an increasing role in both infidelity and its detection. AI tools can be used to create deceptive dating profiles, social media facilitates reconnecting with past partners, and platforms like OnlyFans have become more prevalent. Conversely, technology such as home security cameras and smartwatches are also used to catch unfaithful partners.

Conversely, Crofts identified teachers, accountants, and pharmacists as occupations less frequently associated with infidelity. She suggested that jobs with more structured schedules may present fewer opportunities for extramarital affairs, implying that the nature of the work environment, rather than the job title itself, is a key factor.
