Decoded official Google encoded-polyline paths at their original 1e-5 degree source precision, with every point and ring preserved. Containment groups holes and multipart rings without changing coordinates. This is the official viewer representation, not the legal boundary instrument. Official ArcGIS query returns EPSG:4326; no coordinate precision setting, quantisation or simplification applied. Polygon parts grouped by persistent electorate identifier with every coordinate and ring retained. Source itself is an aggregated representation, not a legal boundary instrument.

EPSG:3857 display projection; original source datums and coordinates are retained. Zoom detail requests the official geographic service; the retained raster and text directory remain available if it cannot load.
