Snooping around Sydney's Airbnb listings reveals a city with more than 36,500 places listed at a higher average price than Paris, London, Melbourne, New York and Hong Kong.

Sydneysiders have flung open their doors and even their backyards to Airbnb, with about a dozen tents, a hammock near Rockdale swinging for $24 per night, and a shed by a pool in Collaroy costing about $70 per night.

The home-sharing platform, which declined to comment for this story, does not share its listings data but an Australian, Murray Cox, opened a window into the company's activity by scraping the website and making it available on Inside Airbnb.

Mr Cox said he found most Airbnb listings were entire homes and flats, many rented permanently.
