A viral TikTok by UK-born mother Layla Subritzky claiming that Australian friendship circles are difficult to break into has renewed a national conversation about social cliques and loneliness, particularly among young people.
Subritzky, who has lived in Australia for almost 15 years, said in the video that socialising in Australia felt different from Britain because groups rarely allow new people to become full members. "In the UK, you go on a night out, you meet someone really cool in the toilet, and you invite them to hang out with your friends," she said. "The following weekend you have a barbecue, and suddenly she's part of the group. ... Well, in Australia, it's very, very strange. You meet someone you get along with, you're introduced to their friends, but you never cross over. You never get invited to the whole circle."
The post drew thousands of responses from both Australians and expatriates, many describing similar experiences. Commenters used phrases such as "no cross contamination" and described social lives segmented into separate birthday parties for work friends, schoolmates and university peers. Several users singled out major cities such as Sydney and Brisbane as places where newcomers feel especially excluded, and some said the social emphasis on where someone went to school makes integration difficult.
Expat respondents called the behaviour "cringe" and "alien," while some local users defended the practice as practical. One user said they "gatekeep" because previous patterns left them excluded after introducing new people, and another said limited free time meant they were selective about adding people to their social calendar. Others pointed to life stages as a turning point: multiple commenters suggested that friendships open up more readily after parenthood, when children provide shared activities and connections.
Beneath the anecdotal debate, researchers say there is a measurable loneliness problem among younger Australians. A University of Sydney study led by Associate Professor Michelle Lim found that more than 40 percent of Australians aged 15 to 25 report struggling with loneliness. The study reported that one in four young people experience loneliness in waves and about one in seven have felt isolated for more than two years.
Lim described the results as "a troubling picture," warning that chronic loneliness can harm both mental and physical health. The research team noted that the experience differs from earlier generations: many young people have frequent social contact but still feel lonely while in groups, reflecting a sense of not belonging rather than a lack of acquaintances.
Social dynamics raised in the TikTok thread echoed themes in the study and in wider public discussion. Some commenters and local residents framed the phenomenon as cultural and generational: Australia was described by one participant as "just one big country town," where geography and shared histories such as attending the same schools shape long-term friendships. That tendency, critics say, contributes to closed networks that are difficult for newcomers to penetrate.
Other explanations advanced in the conversation included practical constraints such as long work hours and high living costs, which limit time for socialising and make people more likely to stick with established circles. A number of young users on city forums described Sydney in particular as beautiful but isolating, reporting that busy schedules, financial pressures and pervasive phone use at public gatherings make forming new connections harder.
Researchers and social commentators say the distinction between social contact and meaningful connection is crucial. The University of Sydney study and the TikTok debate both highlighted situations in which people can be surrounded by acquaintances yet still feel excluded from core friendship groups.
Discussion on social media also revealed defensive motives behind some forms of gatekeeping: a few users admitted to protecting their time and emotional energy after negative experiences, while others framed the practice as cultural preservation rather than deliberate exclusion. Several Australians said newcomers sometimes overcome barriers by being persistent or by entering shared-life spaces, such as parent groups, sports teams or workplaces, where repeated interaction can lead to inclusion.
The viral exchange has prompted renewed calls for awareness about how social habits shape loneliness. With a significant share of young Australians reporting persistent isolation, experts say public health responses may need to address both the structural drivers of loneliness — including economic pressures and geographic isolation — and community practices that influence whether people feel welcome in new social circles.
As the debate continues online, many participants agreed with a common refrain that emerged under Subritzky's video: that feeling excluded from established networks is not simply a personal failing but often a reflection of entrenched social patterns. For those newly arrived or newly single, contributors advised seeking groups built around shared activities and being persistent, while researchers urged broader attention to the mental-health consequences of long-term social disconnection.
