Australia has raised the threat level for travellers to Cambodia as the country's conflict with Thailand intensifies.
The Smart Traveller website now urges a high degree of caution throughout the South-East Asian country, and warns Australians to reconsider the need to travel within several provinces, including the tourist hotspot Siem Reap.
Cambodia has been embroiled in an armed conflict with its neighbour since late July over border disputes that have their roots back to the early 1900s.

It also said Australians should reconsider their need to travel within 50-80 kilometres of the border, including in the larger cities of Battambang and the province of Siem Reap, where the world-famous Angkor Wat temple site is located.
