Just a very slight observation Jo, but, what are the chances of an Australian using mom in their id ?
Aussies still use the British version of the English dictionary, and would use mum, not mom.
I would have also thought that the mid levels wouldn't have all that many Aussie expat families with children, as opposed to family friendly area's like Discovery Bay, Clearwater Bay, Sai Kung, Hebe Haven, Tuen Muns Gold Coast and to some extent, Repulse bay, Shouson Hill, Tai Tam and Stanley.
Discovery Bay, Sai kung and the Gold Coast entertain the largest proportion of Aussie families that have children in the entire territory. If you plan on working in the central Hong Kong Island, Discovery Bay is going to provide you twice as much apartment space, located in much more enjoyable relaxed garden landscaped neighbourhood surroundings, with loads of opportunities for your children to mix with other kids from all over the world.
For reference you can visit the below websites to get an idea of the focus of the area's.
