Activity Introduction

Quick summary: In this lesson, students will view two character stories from Life After The Oasis documentary and reflect on the issues associated with lived experience of homelessness through a Think-Pair-Share thinking routine. Students will then investigate the relative frequencies of homelessness in each state and territory in Australia. They will create scatterplots to represent their collated data to identify trends and make comparisons. Students will also be given an opportunity to reflect on how statistics can be used when investigating social issues such as homelessness.

Life After The Oasis is a 75 minute documentary that explores the issues, interventions and mindsets associated with youth homelessness in Australia. The film revisits characters and stories from the original 2008 documentary The Oasis and how opportunities and experiences have shaped their lives over the last ten years. Find out how to screen or view the film here.

Warning: The documentary and the clips contained in this lesson, contains explicit language, images of drug use and confronting scenes and may upset some viewers. Teachers should use their personal discretion when showing the documentary. This resource deals with the rising problem of youth homelessness and its associated social and personal issues. There may be students in your class who have experienced some of the issues discussed. You are encouraged to arrive at a set of agreements and ground rules for discussion with your class about the best way to approach the issues being covered in a way that recognises the dignity of our fellow classmates.

Learning intentions:

  • Students will use relative frequencies to estimate homelessness in Australia.
  • Students will use scatter plots to compare the numbers of homeless in Australian states and territories.
  • Students will identify and analyse outlier data.
  • Students will understand how statistics and data are one way of highlighting and understanding the complexities of a social issue such as homelessness.

Thought starter: Younger Australians are experiencing increasing homelessness; with 22% of young people experiencing homeless in Australia aged 18 years or younger.

Comparing Homelessness Experiences

1. In your pairs, one person will watch 'Darren’s Story' and the other will watch 'Haley’s Story'. When viewing the clip, make notes about anything you find interesting about your clip in the spaces below:

•  Darren’s Story

•  Haley’s Story

2. Once you have both watched your clips, share the characters' stories with each other and add any further notes to the spaces above.

3. Using the information from Darren and Haley’s stories, list as many similarities and differences between their homelessness experiences.

Similarities Differences





Adding New Data - Northern Territory
