Here is a data trawling website for Airbnb listings in Sydney: https://insideairbnb.com/sydney/#
There are currently 9,700 listings for Sydney on Airbnb alone.
One host has 136 listings and another has 108, etc.
We could identify on websites 58 out of 163 apartments in our building being short-term let.
Airbnb move the location pins so that exact street placements are disguised however I hope this website – Inside Airbnb – helps.
