Collaborating with cartoonist and artist Michael Leunig, Willcock won the 2006 Classical Music Award for Choral or Vocal Work of the Year with excerpts from his work titled Southern Star (his cycle of nine Christmas carols composed in collaboration with Leunig). The carols are composed for 4-part adult voices, or 3-part children's voices and are accompanied by harp - reminiscent of Benjamin Britten'sA Ceremony of Carols. Other major works have been performed by the Tallis Scholars (May 2000) and the Tasmanian Symphony Orchestra (December 1998).
In 2004 he was appointed by the Melbourne Chorale as their first composer-in-residence and that year they performed two new a cappella pieces, Etiquette with Angels (a setting of a poem by another Australian Jesuit, Andrew Bullen) and his Latin setting of Psalm 50, Miserere (considered Psalm 51 in some versions of the Bible). The Melbourne Chorale also performed his John Shaw Neilson Triptych in late July 2004.
