@Thais7. Hi Thais. Its all there on your Service NSW property login, which you should be using to renew each year and I would be encouraging you to check it regularly.
The data appears to be directly fed from ABNB on nights booked, unbooked etc.
If planning ahead then yes, download the bookings into a spreadsheet and use sort functions by date order then total the nights for whatever period you are working on.
Alternatively come out to the regions where 365 nights is still in play (for now) 😉
