Katoomba, a house on 22 Magazine Gap Road

Does anyone have anything, any info on the house called Katoomba, located on 22 Magazine Gap Road? I really want to know about it's first owner, and who owns it right now. This house has been in my childhood neighborhood for as long as I can remember. I lived at 17 Magazine Gap Road (also seeking old neighbors) with my family from 1974 - 1989. No. 17 was owned by my family from 1968 to 1990. No. 11 is still being owned by my best friend's family and No. 21 is also being owned by my Great Uncle. I have found out a lot of history on this road through this site about the history of the houses on the Peak and through my own research of every single lot (FL), Taipan houses that I know of. 

Katoomba, is the ONLY one that I could not find anything on. Despite numerous attempts and over 20 years of research - all leads to a dead end. I am so desperate, because my mother really loves that house. 

Note - Katoomba, Australia - A place high up on the blue mountain in Australia.. The only thing I know is that location does somewhat resembles the place in Australia. But why in Hong Kong, and what Australian ties does this house have?

Here is the google map of it's exact location :

Would really appreciate it if anyone out here could help.

Many Thanks.
