Historical GTFS-Realtime data for bus

Dear Open Data Transport NSW team,

I hope this message finds you well.

I am currently conducting research on bus travel time distribution and am looking for historical GTFS-realtime data, specifically vehicle positions for buses.

I understand that the “Historical GTFS and GTFS Realtime” dataset currently provides access to Metro and Ferry data only. Additionally, I noticed that the dataset at (Historical GTFS Bundles and Timetables - Dataset - TfNSW Open Data Hub and Developer Portal) includes bus vehicle position data for 5 days, which is very helpful. However, for my research, I would need data covering at least one full month to observe meaningful temporal patterns.

While I understand that I can begin collecting GTFS-Realtime feeds moving forward, I would like to ask if there is any archived GTFS-Realtime data for buses (particularly vehicle positions) beyond the 5-day sample that may be available for research use?
