What are the specific NCC 2022 requirements for bushfire-prone area construction in NSW for new homes?

For new homes in NSW bushfire-prone areas, NCC 2022 mandates compliance with Section G5, Bushfire Attack Level (BAL) construction requirements. This involves assessing the property's BAL, ranging from BAL-Low to BAL-FZ, based on vegetation, slope, and fire weather. Each BAL dictates specific material and construction methods for elements like external walls, roofs, windows, and subfloors, aiming to mitigate ember attack, radiant heat, and flame contact. Compliance is typically achieved through AS 3959 or performance solutions, ensuring enhanced resilience against bushfire threats.
