Growth or decline? How did the population of Australia change in the 1800s?

This is a source-based homework task to support student understanding of the NSW History for the Australian Curriculum
Stage 5
Depth Study 1 - Making a Better World
It can be used in either the topic on the Industrial Revolution or Movement of Peoples.
The task can also be used to support the Stage 5 and Stage 6 (Preliminary) Aboriginal Studies syllabuses. The title of the activity is 'loaded': whilst the 1800s saw a tremendous growth in the number of British (then other) peoples moving to Australia there was also a tremendous decline in number of Aboriginal people in many parts of the country. But like all things in history, the conclusions we reach are based on the evidence we have, and this is entirely from one perspective. The activities are designed for Year 9 mixed ability classes but include some higher-order activities including examining an emigration poster for tone and implication and analysing a painting for suggestions about population change in Aboriginal and non-Aboriginal people in Australia.
