The local data in the “What we find in Mermaid Beach homes and units” section is drawn from the third-party sources cited on each card and was last reviewed in September 2026. Those figures belong to the cited sources, not to Knight Electrical Solutions, and we do not claim to have collected them ourselves.
Census figures are Australian Bureau of Statistics 2021 Census data for the Mermaid Beach suburb (SAL) area, SAL31811. They describe the suburb as a whole and say nothing about any individual property. Unoccupied private dwellings are counted as at census night and include holiday and short-stay accommodation as well as homes vacant for other reasons; the figure is not a measure of investment ownership.
Corrosivity categories are general classifications published by Standards Australia in AS 4312 and are summarised above as published by the Galvanizers Association of Australia; we have not reproduced the standard itself. They are indicative of a macro-environment, not a measurement taken at your address, and local conditions including wind exposure, orientation, height and rain washing can shift real exposure considerably. We have not assigned this suburb a corrosivity category.
Statements about Queensland smoke alarm obligations reflect the phased requirements published by the Queensland Fire Department as at September 2026, and statements about safety switch obligations and testing reflect guidance published by the Electrical Safety Office as at the same date. Both are general information, not legal advice about your property, sale or tenancy, and the requirements that apply to you depend on your circumstances.
Each card above combines published third-party data with Knight Electrical Solutions’ own professional interpretation of what that data tends to mean for electrical work in this suburb. The figures belong to the sources cited on each card. The conclusions we draw from them are our opinion, and are not claims made by those sources.
None of this replaces an on-site inspection by a licensed electrician. If something on your property looks or smells unsafe, call 0421 333 034 rather than relying on general information.
