The official govt website listing the new salary can be found here:

You may have already seen coverage of this in the local news but basically the govt is proposing to waive the HK$400 monthly levy (basically a tax which the employer pays to the govt - either in one lumpsum or in four payments spread over 2 years) on new contracts. It isn't completely clear whether this will apply to contracts starting from this September or August so many employers are holding back from signing a new contract until it has been clarified. (This is a substantial savings of HK$9600 over the two years, so it's worth waiting for.)
