Redland City & Bayside includes coastal suburbs such as Wynnum and Cleveland, where many homes were built when asbestos cement products were common. Older fibro beach shacks and post-war houses often used asbestos in roofing, wall cladding, eaves, and garages. While these materials were once durable, long-term exposure to coastal weather changes their condition. Homes close to the shoreline are especially vulnerable, as wind, rain, and sun accelerate surface breakdown.

Salt air is a major risk factor in bayside areas. Over time, salt exposure degrades asbestos cement roofing and sheeting, making it more brittle and friable. Friable asbestos releases fibres more easily, increasing health risks if disturbed during repairs or renovations. Roofing replacements, solar installations, and storm damage repairs are common triggers. Testing is essential before any work begins, as visual inspection alone cannot confirm whether weathered materials remain stable or pose an airborne risk.
