How to Keep Your Business Healthy During the Flu Season (Flu Prevention Tips 2026)

Flu season in Australia typically runs from May through September, and every year it costs businesses significant productivity through absenteeism and presenteeism. According to the Australian Bureau of Statistics, roughly one in three employees takes sick leave during peak flu months. For business owners and facility managers, a proactive hygiene strategy that combines enhanced cleaning protocols, workplace policies, and employee awareness is the most effective way to reduce the impact.

How Influenza Spreads in Commercial Workplaces

Influenza viruses spread primarily through respiratory droplets produced when an infected person coughs, sneezes, or talks. These droplets can land on nearby surfaces where the virus remains viable for up to 48 hours. In an office environment, the chain of transmission is predictable: an infected employee touches their nose or mouth, then touches a door handle, shared printer, kitchen tap, or meeting room chair. The next person who touches that surface and then touches their own face completes the transmission cycle.

Open-plan offices, shared kitchens, and communal bathrooms amplify the risk because more people contact the same surfaces more frequently. Understanding this transmission pathway is what makes targeted cleaning so effective — break the surface-to-hand link and you significantly reduce the rate of spread.

Increase Disinfection Frequency on High-Touch Surfaces

During flu season, standard daily cleaning is not enough for the surfaces that receive the heaviest hand contact. Door handles, lift buttons, light switches, handrails, kitchen benches, fridge handles, microwave buttons, shared phones, and meeting room tables should be disinfected at least twice daily using a TGA-listed hospital-grade disinfectant effective against enveloped viruses including influenza A and B.

Electrostatic spraying technology offers an efficient option for large open-plan offices. The positively charged disinfectant droplets wrap evenly around surfaces, reaching areas that manual wiping misses, while reducing application time by up to 80 percent compared to cloth-based methods. For businesses with 50 or more workstations, electrostatic application during lunch breaks or between shifts provides rapid, thorough coverage without major disruption.

Deploy Hand Hygiene Stations Throughout the Facility

Hand sanitiser dispensers containing at least 60 percent alcohol should be placed at every building entry point, lift lobby, kitchen entrance, meeting room door, and reception counter. These stations serve as a first line of defence when handwashing is not immediately practical.

Bathroom facilities should be checked more frequently during flu season to ensure soap dispensers, paper towels, and hand dryers are functioning and stocked. Empty dispensers break the hygiene chain at the most critical moment. Signage near basins that reinforces correct handwashing technique — at least 20 seconds with soap and running water — keeps the message visible without requiring formal training sessions.

Review Sick Leave Policies to Reduce Presenteeism

One of the biggest contributors to workplace flu outbreaks is presenteeism — employees coming to work while symptomatic because they feel pressure to show up or lack sufficient leave entitlements. Under the National Employment Standards, full-time employees in Australia are entitled to 10 days of paid personal leave per year, which covers both sick leave and carer’s leave.

Businesses that actively encourage unwell employees to stay home, without informal penalties or stigma, contain outbreaks faster and lose fewer total productive days over the season. Clear communication from management at the start of flu season — stating that staying home when symptomatic is expected, not frowned upon — shifts the culture and protects the wider team.

Consider Workplace Vaccination Programs

The Australian Government funds influenza vaccination for people aged 65 and over, pregnant women, Aboriginal and Torres Strait Islander people, and individuals with certain medical conditions through the National Immunisation Program. For the general working population, employers can arrange on-site vaccination clinics in partnership with local pharmacies or occupational health providers.

On-site clinics remove the friction of employees needing to book their own appointment and take time away from work. The cost per vaccination is modest compared to the productivity loss from even one day of flu-related absence, making it one of the most cost-effective preventive measures a business can implement during flu season.
