Meeting Guidelines

  • Microsoft Teams   
  • Sessions will open half an hour before the start, so you can check your connection, and the session will begin promptly at the start time.
  • All the Sessions will be recorded 
  • Discussion within the chat function is encouraged.
  • The session Chair will ensure that the session finishes on time, and that talks are completed within their allocated time. 
  • This is considered very important for the smooth running of a large gathering on-line, and since participants may join a session for individual talks, or parts of the session. 

The following Roles will be allocated for each session 

Chair  Will facilitate the session and keep time. The Chair will also capture a summary of the discussion. The Chair of the first session each day will acknowledge country.  

Prior to the day, the Chair will liaise with any invited speakers about their bio, and liaise with Session Host to obtain a two-point summary of each talk.

After the session, the Chair will coordinate a Session Summary in liaison with the session moderator (using the template provided, and for completion by the end of the week the session was held).

Moderator  Will monitor chat and reflect questions and discussions as time permits – either at the end of the session, of after each talk.  Also, group discussions scheduled for the session will be led by the Moderator, in liaison with the Chair and only if time permits.

After the session, the Moderator will contribute and support the Chair to prepare a Session Summary.

Screen host  Will display the presentations by sharing their screen and step through the presentation guided by the speaker.  The Host will also capture the session Chat.

Prior to the day, the Host will ensure they have received and collated all presentations from all speakers as well as the two-point summaries needed by the Chair.


In preparation for the meeting, Presenters are requested to:

  1. NO LATER THAN THE DAY BEFORE your session: please email your session Chair with 2 key points for the session introduction slide
  2. NO LATER THAN THE DAY BEFORE your session: please email your slides to (For those presenting on Tuesday 15th March – please send on Friday 11th March due to public holiday in Vic and Tas on Monday 14th March).
  3. ON THE DAY – note that you can share your screen and slides – or alternatively the session Host can do this.
  4. AT THE SESSION OPENING – please advise the session Host your preference using chat or email. This will ensure the efficient running of the session.
  5. AFTER the session – email two KEY POINTS from your presentation to the Session Chair. These points will assist the Chair to prepare the Session Report.

All participants

  • Participants are requested to:
      • Please mute when you enter the meeting, and when you aren’t speaking.
      • Please only unmute if requested to by the Chair or Moderator. (Be aware, that participants may be muted by the production team if you forget to mute)
      • Post questions in chat (first preference), or alternatively use the ‘raise hand’ icon in TEAMS. Chat and hand raises will be monitored by the Moderator (during presentations) and by the Chair (during discussion times).
      • Note that all sessions will be recorded including chat.
  • A session summary will be prepared by each session Chair, and distributed to all participants in the weeks following the meeting.
  • Our purpose is to both celebrate and share our new findings and to motivate discussion looking to future challenges. The valuable information captured will be carried forward into our Bluelink annual planning meeting in April.
