Australia's Smartraveller has this advice about local travel in East Timor:
check the security situation, road conditions and the possibility of military operations with local police before undertaking travel. The National Operations Centre (NOC) is staffed by both UNPOL and PNTL officers, and can be called 24 hours a day on (670) 723 0479. You can also get information from the Security Operations Centre (SOC) within the United Nations Integrated Mission in Timor Leste (UNMIT). The centre can be contacted 24 hours a day on (670) 330 4100, extensions 5454/5451 or (670) 723 0635.
(I have just tried the numbers, but they were busy).
