Melbourne Proposes Nighttime Blackout for Digital Billboards to Combat Light Pollution

The proposal emerged from a council-commissioned review which suggests introducing a curfew for illuminated signs situated above ground level. The review identifies three distinct signage areas within the city: the capital city zone, which includes the central business district; Docklands along with commercial and industrial areas; and mixed-use residential zones. Under the proposed guidelines, illuminated signs in these areas would face blackout periods from midnight to sunrise Monday through Thursday, and from 1 AM to sunrise on other days.

Moreover, the council’s proposal stipulates that in areas with lower nighttime pedestrian activity, illuminated signage should be turned off between 11 PM and sunrise throughout the week. This measure is expected to significantly reduce the impact of artificial lighting during night hours across Melbourne.

The need for such regulations stems from the detrimental effects of artificial night lighting on melatonin production—a crucial hormone that regulates sleep cycles. Beyond human health, artificial lighting also poses threats to wildlife, prompting the introduction of national light Pollution guidelines in 2020 to protect biodiversity.

Environmental scientist Dr. Katherine Dafforn has highlighted the extensive research into light Pollution’s impact on both terrestrial and marine animals. Notably, offshore installations such as oil rigs have been recognized for their disruptive lighting effects on surrounding ecosystems.

This proposal aligns with global best practices for managing illuminated and electronic signage to enhance city liveability and sustainability. The Melbourne City Council’s Future Melbourne Committee is set to review the recommendations, reflecting a robust effort to update the city’s signage policy in response to evolving technologies and a better understanding of light Pollution’s broader implications.
