"I think they have every right to do what they are doing," said Rhiannon Coulton, 33, from Australia after she landed at the airport.

"I don't know if this will do any good for them, we will have to wait and see."

Coulton arrived in Hong Kong airport on one of the last planes to land on Monday after authorities announced all remaining flights in and out would be canceled.

As protesters sang and chanted, an occasional muffled announcement could be heard from the loudspeakers above: "All flights have been canceled, please leave as soon as possible."

Flight boards showed row after row of flights with their status reading "canceled."

Underneath one protester had attached a sign: "Sorry for the inconvenience... But we're fighting for survival!"
