An Airbnb revenue forecast is a month-by-month projection of occupancy, ADR and revenue for one property, set beside comparable listings. Buyers use it to test a purchase, operators use it to check an arbitrage lease, and hosts use it to set targets for a live listing.
What I plan around in Melbourne: Australian Open; Formula 1 Australian Grand Prix; AFL Grand Final and Boxing Day Test; Melbourne Cup and Spring Racing. Guests I price for: Event travellers and interstate visitors on 2 to 5 night stays in the CBD, Southbank, Fitzroy and St Kilda. Where I start: A dense event calendar priced a year ahead, winter floors, and per-bedroom benchmarks against apartment supply.
On Airbnb, Booking.com and Stayz I set up PriceLabs or Wheelhouse with every major event loaded a year ahead, levy-aware net targets and winter mid-term options, so your rates follow Melbourne's packed calendar rather than generic seasons, and each venue's crowd is priced by how close you are to it.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Melbourne.
