International Schools in HK - Advice Please

Hi, just chasing some information/advice on getting primary school aged kids into a HK International school. Anyone got experience sending their Aussie kids to the ESF schools? Also, there seems to be 'long' wait lists for most of these schools, would love to know other experiences such as how long it took to get admission to the school of choice & how many other schools you needed to also apply for? Any advice would be much appreciated... Just trying to sort out schooling, accommodation & travel to work. Happy Valley would be a good location, Bradbury school is close by & travel to work would only be around 20 mins but trying to avoid settling on a location to live before finalizing kids schooling options. Obviously don't want excessive travel for the kids to attend school each day.
Cheers

KCIS also has very good reputation in HK and the school fee is comparatively affordable among Intl schools in HK. It is located at North Point on the HK Island.
