Justice Reinvestment in Bourke- Assignment 3 (44198949)


‚ÄčThis model simulates the effect of Police expenditure, Community expenditure and substance abuse (Alcohol and drugs).

This model can be used by community member responsible for making expenditure decision for the community. The variable can be manipulated for see how changes in community engagement and policing expenditure affect other parts of the community.


Youth- The adolescents living in Bourke            

Adult- The adults living in Bourke

Crime- The common crime circulating among the adults of Bourke.

Apprehended- Getting captured by the police

Community Group- Groups formed for the people of Bourke to join. Including development activities, trade-skill learning classes and sports.

Positive Lifestyle- Adults and youth who have improved themselves because of joining these community groups and leading a positive lifestyle.


Community Expenditure - The amount of money spent on community groups to develop skills and keep the adults engaged. The variable can be raised to increase the amount of population (Adult or Youth) joining a community group which can lead to a positive lifestyle.

Alcohol and Drugs - This variable acts as an agent to disengage Adult and Youth from the community.

The Policing Expenditure - The number of money spent after police. This variable can be changed to affect the number of people getting apprehended.


1) 3000 People living in Bourke

2) External Influence - Community groups, Police and Substance abuse

3) 70% of the population are Adult and 30% are Youth

4) Crime- 600

5) Apprehended - 

6) Community Group - 300

7) Positive life - 100

8) Jail - 480


Positive Lifestyle lead by the community-      Setting the Community Expenditure to a high 80, policing factor to a medium 50 and Substance abuse to a low 30 we will see a surge of positive lifestyle.


High Rate of Engagement- An increase in the Substance abuse variable to 10% shows crime and people in jail increase but the ratio of people engaged in community groups is much higher.

CRIME RATE (HIGHEST) - If Community Engagement Expenditure and Policing Expenditure are reduced to zero the amount of crime increases significantly over time and the amount of people in jail reduces to near zero.



A combination of policing and community engagement expenditure is the best solution for the people of Bourke.The policing will gradually reduce the amount of crime and the community development programs will help create a positive lifestyle.

For the most effective outcome, an increase in policing is needed as well as investments in community engagement activities.
