Foreign tourists roaming without wearing face masks on the Indonesian resort island of Bali are being subject to perform push-ups as a punishment, reported AFP.

Videos surfacing on social media show tourists in T-shirts and shorts being made to do the exercise in sweltering tropical heat as masked security officials stood over them.

Notably, Bali authorities made wearing a face mask in public mandatory for all visitors last year as Indonesia battled COVID-19 outbreak.

However, many foreigners have been caught without face masks recently, said security official Gusti Agung Ketut Suryanegara.

Till now, over 70 people have paid a fine of 100,000 rupiah ($7), but about 30 others said they did not have the cash, so instead, they were ordered to do push-ups.

People not carrying a mask had to do 50 push-ups, while those who were wearing their mask improperly were punished with 15.

“At first, they would claim that they didn’t know the regulation,” Suryanegara told AFP. “Then they said they forgot, or that the mask was wet or damaged.”

Bali’s authorities have also warned that foreigners who breach virus protocols could be thrown out of Indonesia, although so far there have no reports of anyone being deported for failing to wear a mask.

Bali, which has been hammered by the pandemic, remains officially closed to overseas tourists but is home to many long-term residents from abroad. Foreigners living elsewhere in Indonesia can still visit the island.
