TigerCrew,
The laws before the election regarding AWAs are the same as the laws today regarding AWAs. Laws don't just automatically change when the government changes. An act of parliament is required to change any laws.
Workchoices is good for business, so is therefore good for the economy, and, what is good for the economy is good for all Australians. The new government will be well aware of this and, to a large extent, in agreement with this view - but of course, will never say so publicly.
The challenge for them is to scrap Workchoices and AWAs without actually scrapping them. Naturally, they will find a way to successfully do this.
