Here are 328 Australian weather stations that are not compliant with Bureau of Meteorology specifications for siting.
Site compliance is important because temperature data from these stations is liberally reported in the media especially if hot or cold records are set. They also contribute to AWAP (the Australian Water Availability Project) and ADAM which produce maps of present and past temperatures. As well, data from these stations is used to homogenise data at stations in Australia’s ACORN-SAT network, which are used for showing trends since 1910. Finally, this data is exported to be used by international databases (GISS, CruTem4) for regional and global climate analysis. If the data is affected by site specific factors, e.g being too close to a road, this may affect the quality of the analysis.
I am agnostic as to the overall effect of these poorly sited stations. Maxima at some sites may be artificially low, or minima may be artificially high, and this may vary with seasons and rainfall. Analysis and comparison of temperatures will come later. My focus here is to show the large number of modern stations whose data may be unreliable.
The quality of these non-compliant stations varies. While some are truly horrendous, others are not nearly as bad, but all fail on one or more specifications.

Ken I have a vague memory of commenting on the BOM station at Canberra Airport. But Canberra is not in the list. Is my memory wrong ?

Canverra is not on the list. I think you commented on Canberra re another station.

Also congratulations on pulling this all together : arranged by state or territory with a link to each BOM station. It makes it easy to check out each one.
I do have a suggestion though. Please include a BOM station which is compliant with their guidelines to illustrate that they do exist and that the guidelines can be complied with by BOM

OK Ken… My memory is vague on this.
