Woman in a garden in Singapore in the mid 1960s

A portrait of a woman standing in a garden in Singapore, taken by an officer stationed at the RAF base ( RAF Seletar) on the island in the 1960s. I assume (possibly wrongly) that this is the wife of the photographer, but I don’t know any details of either the woman or the photographer. If anyone who was stationed at the base in the mid-1960s knows the name of this woman it would possibly help a lot in identifying the photographer and fixing the date of the picture. Please let me know via the comments form below if you can offer any help.
