I scrape feeds from a variety of sources, and publish them to APRS-IS under the callsign VK1XT-15.
The feeds currently available are listed below.
The aprs-238001:aprs BigQuery dataset contains an almost complete copy of every APRS packet seen on APRS-IS in Australia (and New Caledonia) since late April 2019. Data will be retained indefinitely, budget and storage costs permitting.
The dataset is public, but you'll need to use your own Google Cloud Platform account to explore it.
