Inside-Out classes where RMIT’s criminology and justice students and incarcerated people undertake an elective and learn as equals were introduced in 2015 by Dr Martinovic. These now offered at seven prisons. 800+ university students and incarcerated people have completed it. Post Inside-Out incarcerated people apply their knowledge in advocacy by transitioning into prison-based Think Tanks and subsequently community-based Think Tank upon release. There are six prison-based Think Tanks and a community-based Think Tank with 125+ active members. Created and led by Dr Martinovic these Think Tanks have engaged in 100+ consultations with stakeholders about finding solutions to complex issues in the justice sector. ‘Prison-based and Community-based Think Tanks’ are an Australian first initiative which has resulted in systemic change led by the voices of incarcerated/ex-incarcerated people. The knowledge exchange within Think Tanks plus the robust consultation with stakeholders, has had a significant impact on the Department of Justice and Community Safety who have implemented many of the Think Tanks’ recommendations, and now have a strategic policy to include the voices of incarcerated/ex-incarcerated people in operational/procedural decision-making. The Think Tanks however are not just ‘programs’ for incarcerated/ex-incarcerated people, these are the only safe spaces for them to openly and honestly discuss their deep personal systemic experiences, engage with stakeholders, and collaboratively design innovative strategies to improve the justice system. The impact is hence priceless -- less judgmental, more inclusive and collaborative society providing real opportunities for disadvantaged and marginalised incarcerated/ex-incarcerated people, thereby resulting in a safer society.
