Australian river heights + gauge rainfall near any AU location — live CC-BY-licensed gauge
observations from the Bureau of Meteorology's Water Data Online (keyless KiWIS API); the
Australian counterpart of water_levels (US USGS). Per station: latest river level (m) with a
~3 h rising/falling/steady trend, or rainfall totals (mm over 1/6/24 h ending at the latest
reading), plus real observation timestamps + ages, distance, the data owner and the exact
attribution string. `location` = an AU preset ("brisbane" default, "sydney", "melbourne",
"adelaide", "hobart", "darwin", "canberra", "perth") or a "lat,lon" string; explicit
`lat`/`lon` override. `kind` = "river" | "rain" | "both". Only stations whose data owner is
CC-BY-listed (Table 1) in the BoM rain/river licensing statement are served — per-station
owner attribution carried in provenance, exclusion counts reported, WA coverage honestly
partial. Observational data ONLY — not a flood warning product; official flood
warnings/watches are issued by the Bureau at bom.gov.au/australia/warnings.
Every value is returned in an Ed25519-signed, provenance-stamped envelope (source and observation time) you can verify offline against /.well-known/keys, no account required.
