Question 1
a) The bar chart indicating the value of exports from Australia to major trading partners is
captured as follows.
b) The pie chart indicating the percentage exports from Australia to major trading partners is
captured as follows.
For 2004/2005 For 2014/2015
c) The key observations that can be derived on the basis of comparisons between 2004-2005
and 2014-15 exports from Australia are summarised below.
 There has been a sizable increase in the percentage of Australian exports headed to
China during the period under consideration. In the process, China has replaced Japan
as the largest destination for Australian exports and thereby has assumed a pivotal
role in the Australian economy.

 The comparison of the respective bars for each of the two countries for the two years
under consideration clearly outlines that exports from Australia in absolute terms has
increased to each of the given destinations except United Kingdom. It may be
worthwhile to analyse the same in detail. Additionally, the rise of exports to New
Zealand during the 10 year period is quite miniscule which comes as a surprise
considering the two countries are neighbours.
