Volunteer burnout advice needed
I'm a volunteer in a "Friends of" group for local garden but I'm in a bit of a dilemma. Our group numbers have dropped over the years to the point where there is now only 4 committee members. I'm finding myself burned out and considering stepping back from the group however if I leave it's highly likely the group will need to wind up as they won't meet their model rule requirements for the number of committee numbers and office bearers. The group is also a registered charity so is required by law to have a certain number committee/board members.
I'm an office bearer and there is literally nobody else to take my position. Attempts to bring in new members have been unsuccessful due to lack of interest. I would feel incredibly guilty if the charity shuts down just because I leave.
Is there an organisation in Australia that I can go to for advice in this situation?
