High demand of IS auditor in Financial Hub Country

Recently, one of my friend visit Hongkong for one of firm project. He feels very surprised when reading Hongkong newspaper which announcing job vacancy for IS auditor almost in 4 pages. Yes 4 pages, Hongkong which act as Financial Hub in global competition, really need a lot of IS auditor. Instead of very long working hours, of course high benefit and salary will be given there.

I'm not so expert in this matter, but do you guys has any opinion. Actually how much IS auditor demand in Financial Hub Country such as Singapore, Dubai, Hongkong, Holland, UK or US?
