Darwin's tropical climate makes hygiene harder. Humidity drives mould and bacteria, the wet season tracks moisture through entries, and high use bathrooms and kitchens need consistent attention to stay safe.
There is a duty of care angle too. Supported accommodation houses people who may have higher health vulnerability, so infection control, safe products and proper waste handling matter more than in a standard office.
Presentation also affects trust. Families, support coordinators and auditors all notice the state of a facility, and a clean, well kept site signals a well run service.
