Learn moreAbout Newhaven's Climate Risk Profile
Newhaven, situated in Victoria's Bass Coast Shire, is a coastal community with a growing population and a strong connection to its natural environment. This unique setting, however, exposes it to a range of climate-related risks that are projected to intensify in the coming decades.
The most pressing concern for Newhaven is its coastal exposure. The suburb is vulnerable to the impacts of sea level rise, increased storm surge activity, and ongoing coastal erosion. These factors pose a direct threat to coastal infrastructure, properties, and natural ecosystems, necessitating robust coastal adaptation strategies.
Bushfire risk is another significant consideration. Newhaven is bordered by areas of coastal heathland and grassland, which can act as fuel sources during hot, dry periods. The increasing frequency of extreme weather events exacerbates this risk, making effective fire preparedness and management essential for the safety of residents and properties.
While flood risk is currently assessed as moderate, primarily linked to intense rainfall events and potential minor inundation from nearby waterways, this risk is not static. Climate change is expected to alter rainfall patterns, potentially leading to more extreme downpours and increasing the likelihood of localised flooding. This underscores the need for effective stormwater management and land-use planning.
Heatwaves are also a growing concern. As average temperatures rise and the intensity and duration of heatwaves increase, Newhaven residents will face greater risks to health and well-being, particularly vulnerable populations. Measures to mitigate urban heat island effects and ensure access to cooling centres will become increasingly important.
Addressing these multifaceted risks requires a coordinated approach involving local government, state agencies, and the community. Investing in adaptation measures, promoting climate-resilient development, and fostering community awareness are key to safeguarding Newhaven's future.

Frequently Asked Questions
What is the primary flood risk in Newhaven?
The primary flood risk in Newhaven stems from coastal storm surges and king tides, exacerbated by sea level rise. Localised flooding from intense rainfall events is also a concern, particularly in low-lying areas near the Bass River.
How close is Newhaven to significant bushfire fuel sources?
Newhaven is situated adjacent to coastal heathlands and grasslands, which are identified as bushfire-prone areas. This proximity means there is a significant risk of ember attack and direct flame contact during bushfire events.
Will sea level rise significantly impact Newhaven properties?
Yes, projections indicate that sea level rise will increase the risk of coastal inundation and erosion in Newhaven, particularly affecting properties closest to the coastline. This is a key driver of the high coastal risk score.
What measures can homeowners take to prepare for heatwaves in Newhaven?
Homeowners should ensure adequate insulation, install efficient cooling systems, maintain trees for shade, and have a plan for staying cool during heatwaves, such as using community cooling centres or visiting cooler areas.
Does Bass Coast Shire Council have a climate change adaptation plan for Newhaven?
Yes, Bass Coast Shire Council has a climate change strategy that addresses risks across the shire, including coastal adaptation, bushfire preparedness, and sustainable development. Specific actions for Newhaven are outlined within this broader strategy.
What is the projected increase in extreme rainfall events for Newhaven?
Climate projections suggest an increase in the frequency and intensity of extreme rainfall events for the Gippsland region, including Newhaven. This means a higher likelihood of flash flooding and increased strain on drainage systems.
