I live in Singapore and have been here since '98. TheFlyingCamera's recommendations for film are spot on. Ruby for Ilford, Cathay Photo Kodak & Fuji, Konata (same building) Fuji film. What do you want to photograph, is certainly an important question. Little India and Chinatown are good people places reflecting some more traditional lifestyles - wander around, walk down alleys, its all safe. Postcard type shots; Gardens by the Bay and around the general Marina Bay area.
These are some examples of what you can shoot; Any question just ping me.
