Start with Y=F(CIGXM) and go through each of those providing a few anecdotal stories you have read from newspapers and any data you have come across, for example:
'In April 2012, China announced lower than expected growth at 8.1% which could potentially impact on Australia's commodity exports.'
Draw on your textbook to link in some of the impacts on U/e, inflation, and Ext Stab. Some examples include lower inflation due to weakening of consumption, the possibility for increasing unemployment, and a possible weakening of the CAD due to weaker exports. Etc etc.
