Some of the difficulty with this answer is that it depends in part on jurisdictions. There are a number of codes that are due to commence on 1 January 2012. There are others, such as the mining codes, that it is envisaged will commence around mid that year. Further to that, there are also other codes that are in various stages of development. The complication with the mining codes is that the way some jurisdictions deal with mining differs between jurisdictions as well.
