I wouldn't expect a fast or useful answer from the BOM.
I have been looking at Weather Underground for real time very local data historical weather data particularly rain accumulation graphs. You often even in rural areas have a wide selection of reasonably accurate low cost weather stations and you get very frequent updates you just don't get from the BOM and data that isn't available in Windy like rainfall history. About 5% of the stations are lower quality results but looking at the map and comparing nearby monitors output you can quickly eliminate them. It is a reasonable crowd sourcing weather project that fills a gap that Windy or BOM don't provide.
