The Australian government has issued a travel advisory urging its citizens to exercise caution when traveling to the Philippines, particularly in Mindanao, due to security risks.

In the advisory, Australia warned of a "high degree of caution" across the country, citing threats of terrorism and violent crimes.

"There's an increased risk of demonstrations and civil unrest following recent events. Avoid protests and large gatherings as they may turn violent," the advisory stated.

It also warned of potential disruptions to transport and essential services, advising travelers to monitor the media and follow local authorities’ guidance.

The advisory highlighted the risk of terrorist attacks in public spaces such as airports, public transport, hotels, shopping malls, restaurants, major events, places of worship, and tourist areas.

Australians were strongly advised against traveling to central and western Mindanao, including the Zamboanga Peninsula, Sulu Archipelago, and the southern Sulu Sea, due to the "very high threat of terrorism and kidnapping."

This advisory comes five days after the US Embassy in the Philippines issued a similar warning to American citizens, citing an increased risk of kidnappings for ransom in Western Mindanao, particularly in Zamboanga del Norte, Zamboanga del Sur, and Zamboanga Sibugay.

"Terrorist and criminal groups continue to target foreign nationals, including US citizens, with kidnappings, bombings, and other violent attacks," the US advisory stated.

The US Embassy also noted that American government employees require special authorization to travel to most parts of Mindanao, excluding Davao City, Davao del Norte, Siargao Island, and the Dinagat Islands, due to limited emergency assistance capabilities in the region.
