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
