Peak Weather Station Stereo

My recent acquisition showing the Victoria Peak Weather Station.  The stereo photo was apparently taken from the Peak Signal Station (Flagstaff) at a certain occasion where a dozen of people in formal dressing could be seen.  We can also see coolies and sedan chairs resting on the footpath.  

I do not have the date for the photo and just put 1900 as a first guess.  Any idea on the possible date and what the occasion might be?
