Hazard history for a location

Each row is one query. Declarations are counted once per AGRN, so an event three authorities recorded counts once rather than three times.

Molesworth Street, Lismore

The case that proves the two lanes are both needed. The February 2022 flood put this street under water, and the observed lane holds no record of it at this precision. It is here through the declared lane, as AGRN 1012.

• Recorded nearby: 10 flood, 4 bushfire, 3 storm, 2 grass fire
• How those records were located: 12 points (6 placed exactly, 6 with precision unstated) and 7 mapped areas

Great Western Highway, Blackheath

Mapped fire extents rather than points. The Grose Valley fire and the Black Summer boundaries both cover this location, and 16 of the 247 archive records carry no date.

• Recorded nearby: 239 bushfire, 31 storm, 6 burn off, 2 flood
• How those records were located: 278 mapped areas: 245 fire extents and 2 council-wide flood areas with precision unstated, and 31 official warning areas
• 16 of them carry no date, so none is shown for those records

Oxlade Drive, New Farm

What a large count really means. 2,452 of these 2,508 records sit at a postcode centroid, so they are near this postcode, not near this street. A count without its precision would badly mislead. The 16 mapped flood extents are different: they are the Brisbane River floods of 1974, January 2011 and February 2022 as the agencies drew them.

• Recorded nearby: 1,013 vehicle accident, 802 other, 180 structure fire, 154 rescue, 129 other fire, 92 hazmat, 50 vehicle fire, 38 bushfire, 21 flood, 18 storm, 11 grass fire
• How those records were located: 2,452 points at postcode precision, 39 points placed exactly and 17 mapped areas (16 flood extents with precision unstated, 1 official warning area)

Mundaring Weir Road, Mundaring

Depth. The record here runs back to the 1937 fire season, and fire management shows up as clearly as fire: 253 of the 603 records are planned burning, not emergencies.

• Recorded nearby: 347 bushfire, 253 burn off, 3 other
• How those records were located: 601 mapped areas (599 fire extents with precision unstated, 2 official warning areas) and 2 points placed exactly

Anzac Highway, Glenelg East

The honest negative, and an honest gap. No disaster declaration has ever covered this local government area. 400 older road-crash records nearby count the crashes at one spot over several years and carry no date, so none is invented for them. The dated records are the 62 the live feeds have logged since April 2026.

• Recorded nearby: 416 vehicle accident (400 with no date), 26 other, 9 rescue, 6 tree down, 3 hazmat, 1 structure fire, 1 vehicle fire
• How those records were located: 462 points: 400 with precision unstated, 62 placed exactly
• 400 of them carry no date, so none is shown for those records

Three things decide whether a count means what it appears to mean, and every response carries all three.

• Precision. A record at postcode precision sits at a postcode centroid, which can be kilometres from the event. Almost all of the New Farm records above are postcode centroids, so they are near that postcode rather than near that street.
• Dating. Some records carry no date: their source gave none or only a placeholder, the record counts events over several years, or we have not yet carried over a date its source gave. Those records are returned and flagged rather than dropped or given one, which is why 400 of the Glenelg East records carry no date.
• Coverage. The archive holds 4.5 million records, of which 3.7 million carry a usable location. A record with no location cannot appear in a location query at all.

Some records are left out on purpose. Medical calls are left out for privacy. Alarm calls are left out because an alarm is not a hazard: the agency either found no fire or did not record the outcome, and a real fire is recorded as a fire. Road and traffic feeds are left out because they record roadworks, closures and traffic, not hazards.

Mapped areas stay in. A fire’s footprint or an official warning area is a record of what reached a place, often a better one than the incident’s own point, so one fire can be counted once for each source that recorded it.

Declarations are matched to the local government area containing the point, not to the address. A declaration with no published end date has not been shown to have ended, and that is not the same as being in force.
