Australians may prefer not to live too close to others, yet fresh data indicates they still hold firm expectations for those living nearby, even if these standards remain unspoken.

Research involving over 2000 people, conducted for Youi Insurance, identifies noise as the top neighbourhood complaint, with 63 per cent naming the need to reduce sound after set hours as a key unwritten guideline.

Close behind comes the habit of using power tools at unsuitable times, cited by 48 per cent as something that should be avoided early or late in the day.

Sound issues also drive the most disputes, making up 21 per cent of reported bad neighbour encounters, and they represent the behaviour most likely to prompt direct conversation, at 52 per cent.

Quiet periods are well understood. Two-thirds of respondents, or 66 per cent, set the limit before 10pm on weekdays, while 64 per cent show slightly more flexibility on weekends.

The findings represent the next part of Youi's Unofficial Series, building on prior driving etiquette work, and have been shaped into the Australian Unofficial Neighbourhood Etiquette Act, 2026.

The Act outlines five main points that matter most to residents:

Excessive Noise and the Right to a Good Night's Sleep
Parking Conduct and Access Protection
Neighbour Acknowledgement Protocol
Pet Conduct and Control Regulation
Privacy Boundary and Non-Intrusion Standard

Parking problems rank second, as expected for anyone returning to find a vehicle blocking access.

Over half, or 55 per cent, would raise the issue if a neighbour obstructed their driveway, an action that is also against the law, while 60 per cent view avoiding such blocks as a standard neighbourhood courtesy.

Baby Boomers hold the strongest views on parking manners, with 71 per cent seeing driveway clearance as essential and 45 per cent believing better habits would improve local ties.

The results point to neighbourhoods relying more on shared customs than formal rules. Some 54 per cent agree their area follows unwritten standards, and 58 per cent favour neighbours who stay polite yet maintain distance.

Youi chief customer officer Anthony Antonucci noted the data reveals Australians aim to be good neighbours while preserving personal space, with noise marking the clearest boundary.

He added that younger people recognise these standards, at 65 per cent for Gen Z, yet apply them less often, whereas Baby Boomers lead in consistent adherence.

Social researcher and futurist Ashley Fell observed that Australians are reshaping community ties in an individual-focused era, favouring easy and non-intrusive interactions.

Getting these details right brings benefits, as 53 per cent report that nearby neighbours increase feelings of safety and support.

Keeping sound levels low, parking correctly, and offering a simple greeting can help avoid long-term tension in shared spaces.
