The Society held its Annual Dinner for 2011 at St Paul's College, University of Sydney on Friday 18 February 2011. Our guest-of-honour was the Governor of NSW, Her Excellency Professor Marie Bashir AC CVO, one of our two Patrons and a long-standing supporter of the Society. We were also pleased to have three Deans of Science from universities in Sydney present. In her Occasional Address Her Excellency made reference to the antecedents of the Society and the work of one of her predecessors, Governor Lachlan Macquarie, in creating a climate in which Societies such as ours might germinate. We appreciate her support and that of the unbroken line of her predecessors.​
