To be frank, the enhanced cleaning protocol is more of a “protocol” and less of an “enhanced”. If you already clean your listings to a high standard, then there is very little additional work involved. The most onerous task may be cleaning flatware and cookware between guests, especially if you don’t have a dishwasher.
The ventilation time (buffer) is for your protection, so essentially you do what you’re comfortable with.
It takes me around ten minutes to do the “sanitisation” element, maybe a bit less actually, for a 60m2 one bed apartment. An aerosol can of alcohol sanitiser is around €1.50 here, and that’ll be good for a couple of changeovers.
Unless you’re refusing to sign up as a matter of principle, I’d suggest you take a second look through the guide (most of it is just common sense), and look to see how you could adapt the processes you already have in place.
Sadly, this where Airbnb is letting itself down. It’s using a one size fits all protocol, when in reality they should be constantly updating and adapting it based on Continental variations. It took them long enough to remove the curtains and soft furnishings nonsense, a task that I’m sure in reality very few hosts complied with.
The mask issue isn’t a problem for us, it’s the law here and you’re fined if you don’t wear one in public, or when dealing with the public.
Be prepared for a steep learning curve, especially if Airbnb is the only OTA you’ve advertised on. A half way solution may be VRBO, you can opt out of the IB and have request to book, although I’ve no idea if folks use it down under
