AirBnB claimed 'ONLY' 1-2% of properties in Australia were AirBnB's.
My first thought is that actually seems like a lot, especially as it's 1-2% of ALL housing stock, not just rentals.
I did some calculations. Total Aus housing stock = ~10,000,000 2% (I'll assume the higher figure since the lower suits their narrative) = 200,000 200,000 ÷ 8 states & territories = 25,000
So that would potentially be an extra 25,000 rental properties for every state/territory.
Currently advertised on RealEstate.com.au are ~2260 rentals for all of South Australia. Adelaide metro area has ~1700 or 75% of the state total. With an average listing time of 3 weeks, we could extrapolate ~ 29,000 properties rented out in a year. So if we were to add an extra 25,000 ex AirBnB's that would mean an 85% increase in rental properties available over a year.
