That law isn't doing much good. I looked up one New York City hotel (like the OP) on the linked Australian site, and it was exactly like the US site. The resort fee was not part of the AirBNB price, only under "Show more" at the bottom of the hotel description did it state:

There is a 𝐅𝐚𝐜𝐢𝐥𝐢𝐭𝐲 𝐅𝐞𝐞 𝐨𝐟 $𝟒𝟎.𝟏𝟔 𝐩𝐞𝐫 𝐧𝐢𝐠𝐡𝐭 that will be charged upon arrival. This includes WIFI, local and long distance calls, fitness center access, 1 Citi bike daily pass, and a $10 Food and Beverage credit daily.
