AirAsia flies to more than 140 destinations in the Asia Pacific, with two-thirds of its Australian passengers connecting to other destinations through the network.
In February, the budget airline announced it would launch a new service between Bangkok, Thailand to Brisbane, Australia from June.
Collective Shout, a grassroots movement against the objectification of women and sexualisation of girls in media, said the latest campaign ads were a “dog whistle for sex tourists”.
"Bangkok is a hub of sexual exploitation of women and children, and 250,000 western male sex tourists visit Thailand every year," spokeswoman Melinda Liszewski said.
One of the adverts was spotted at the Brisbane Airport and posted to Reddit.
Brisbane City councilor Kara Cook told Nine News "it should never have appeared on our city's streets".
AirAsia has issued an apology for the ads, and said they would removed.
An AirAsia spokesman said: "We take community feedback extremely seriously and sincerely apologise to those who have raised concerns".
"The campaign has since ended and our media partners had the last of these advertisements removed yesterday."
