Well there's other schools on Kowloon side:
- Beacon Hill School (
http://www.beaconhill.edu.hk) - probably the closest to Shatin
- Bauhinia School (

- Kowloon Junior School (
http://www.kjs.edu.hk/)
- Clearwater Bay School (

Hope that helps! These are all ESF schools. I'm not sure if there are any other international schools in the area as well
