Insurance Costs Analysis
Insurance costs for properties in Mascot, New South Wales, are influenced by the area's exposure to flood, bushfire, storm, and other climate hazards. Insurers assess risk at the individual property level — two nearby properties can have meaningfully different premiums based on their specific hazard exposure.
Key drivers of premiums in Mascot include flood zone classification (which affects whether flood cover is available and at what cost), bushfire attack level (BAL) ratings for properties near vegetated areas, and storm risk based on wind zone classification and hail exposure.

Mascot (postcode 2020) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are coastal inundation (6.2% of land in high-risk zones), surface flood (5.8% of land in high-risk zones), bushfire (5.1% of land in high-risk zones). Exposure is not uniform across Mascot — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
