Short-term letting site Airbnb has taken over up to 15 per cent of potential rental homes in the beachside suburbs such as Bondi and Manly, cutting the number of properties available to long-term renters in parts of Sydney.

But the popularity of short-stay accommodation in desirable coastal and inner city pockets has not made it more difficult to rent throughout Sydney as a whole, new research has suggested.

An Australian Housing and Urban Research Institute report, published on Thursday, looked at how short-term letting platforms like Airbnb had reshaped housing markets in Sydney and Melbourne.

It said short-stay accommodation platforms were "probably not significantly worsening rental affordability across our major cities as a whole" but had an impact on "availability of rental properties in high-demand inner city areas with significant tourism appeal".
