Further your learning

Take a look at our upcoming workshops and masterclasses related to essential family violence intervention skills in 2022.

We are open for business despite Covid 19

For many of us, the world has changed dramatically as we adapt to the changing environment caused by Covid 19. HMA has delivered high-quality in-room and online training for a long time and will continue to do so in the months ahead. While delivery has gotten harder, there are great opportunities in the months ahead to upskill staff while they are working remotely and away from the interruptions of daily practice (although for those in lockdown balancing children at home, working from home, and keeping Netflix on hold, can be a challenge).  We have a number of useful eLearn packages that will be of interest. These include:

  • A six-session Motivational Interviewing Program
  • Assessing Men for Family Violence Interventions
  • Family Violence Four Part series
  • Case Formulation of Offenders
  • Helping People Change
  • Motivate Me to Learn

Assessing increased risk of family violence in a Covid 19 Environment

We have been acutely aware of the additional risk of family violence that’s emerging as people face the challenges of living in a Covid 19 environment. We have developed the resource below to assist workers to assess their caseloads and develop direction to conversations that will enhance family safety and wellbeing through this period of time.
