The NSW-ACT Branch activities are co-ordinated by a committee. The committee is made up of elected office bearers, nominated before and announced at the Branch Annual General Meeting. The Committee meets monthly, usually in the third week of the month, at a venue decided upon by the committee.
The Branch is actively involved in promoting all fields of Microbiology through various means such as organising and supporting regular meetings which provide a venue for a variety of presentations by local, national and international speakers. The Branch supports many Awards, publishes a monthly newsletter 'Syntrophy' and promotes Microbiology at schools, TAFE's and universities.
