Geez, that seems like a hard question but, i'll give it a go.
Speak about imports and exports and how that has been affecting quality of life, the CAD, governments influence over the multinational corporations which have placed themsleves over the government and have a major influence over foreign investment in Australia.
Another major area is where our trade is going as today much goes to Asia and North America. Also speak a bit on trade agreements and how Australia has been the most enthusiastic to take on the WTO policies of free trade. This has led to greater integration with dregulation and lifting of trade barriers which has allowed us to integrate faster.
Structure this by each factor which influences it, separate trade and finance, a paragraph on policies to integrate and how they impact on society.
