Reviewing the effectiveness of the Community Liaison Group
Sonya Leahy 25 September 2018
Why a review? To ensure:
• CLGs are effective as they can be
• Both CRL and its CLG members are getting the most out of the meetings.
• CLG membership is reflective of the surrounding community
• CLG members can review and input into plans easily and effectively, as required under CRL’s consent conditions.
40
What do we want to review? • Is membership reflective of the community?
• Options for wider representation and improved attendance
• Are meetings meaningful for members?
• Member’s thoughts • Can CLGs be utilised more? • Options to improve the documentation review process
• Frequency of the meetings
41
What ideas do we have? • Establish Terms of Reference • Review membership
• Tailor CLG meeting content • Explore better ways of providing information and receiving feedback on project plans
• Meet more often • Make CLG members more visible to others in the community
• Creating visible online access to CLG presentations and minutes.
42
What next? • Develop a new CLG strategy • Canvas members to understand what does and doesn’t work for them
• Invite a Local Board representative to meetings
• Discuss all the proposed changes with members
