The quartet performs on a matched set of string instruments hand crafted by Giovanni Battista Guadagnini between c.1743-1784 in Italy. The earliest of these is a cello (c. 1743), and a violin (1748-49), both made in Piacenza. The viola (1783) and another violin (1784) were made in Turin.

The ASQ regularly tours Australia and the world. The current members are Dale Barltrop (violin), Francesca Hiew (violin), Christopher Cartlidge (viola) and Michael Dahlenburg (cello).

Guest artists have included pianists Angela Hewitt, Angela Lam and Piers Lane, mezzo-soprano Anne Sofie von Otter, clarinettists Michael Collins and Ashley Smith, violist Brett Dean and cellist Pieter Wispelwey.

In 2014-15, a documentary Highly Strung was made about the ASQ that documented the break-up of the quartet as it was then, plus the making of a copy of the cello by Italian luthier Roberto Cavagnoli. The documentary was made by acclaimed film-maker Scott Hicks. It introduces us to Ulrike Klein, a board member of the ASQ, and the members of the quartet.^[1][2][3]
