Visitors to Bali will not be risked by Indonesia's newly ratified criminal code, according to the island's governor, who dismissed concerns that revised laws, which include articles criminalizing sex outside marriage, might stop tourists from visiting the island.

The controversial bill, which also prohibits cohabitation between unmarried couples, was passed by Indonesia's parliament last week.

Seeking to reassure visitors, Bali Governor Wayan Koster in a statement on Sunday noted the new laws, which come into effect in three years, could only be prosecuted if there was a complaint by a parent, spouse, or child.

Those who "visit or live in Bali would not need to worry with regard to the entry into force of the Indonesian Criminal Code", he said.

The governor said provisions in the criminal code on this issue had been altered from an earlier, stricter version so as "would provide a better guarantee of everyone's privacy and comfortableness."

Bali's government would ensure "there will be no checking on marital status upon check-in at any tourism accommodation, such as hotels, villas, apartments, guest houses, lodges, and spas," Wayan said.

Wayan also denied what he said were "hoax" reports of cancellations of flights and hotel room bookings, adding that data from travel agents, tour and accommodation operators, as well as airlines, showed the number of people set to visit Bali from December 2022 to March 2023 had increased.

Bali is the center of tourism in Indonesia and the tourism association is targeting foreign arrivals on the predominately Hindu island to reach pre-pandemic levels of six million a year by 2025.

Decades in the making, legislators hailed the passage of the criminal code as a much-needed overhaul of a vestige of Dutch colonial rule. Officials say it aims to uphold "Indonesian values" in the world's largest Muslim-majority nation.

But Maulana Yusran, deputy chief of Indonesia's tourism industry board, said last week the new code was "totally counter-productive" at a time when the economy and tourism were starting to recover from the pandemic.

The United Nations has also expressed concern over threats to civil liberties posed by the criminal code, which also includes laws that make it an offence to insult the president, the national flag and state institutions.
