The artistic culture of Beaumaris has extended beyond visual arts into theatre, music, and design. In 1953, British immigrants Bill and Angela Martin, along with twenty other couples, transformed the attic of Talbot House on Cromer Road into a small theatrette. There, they staged English comedies such as The Shop at Sly Corner and Blithe Spirit, donating proceeds to charity. By the late 1950s, the Beaumaris Players relocated to the purpose-built Stan Hawken Hall on Illaroo Reserve at Wells Road, evolving into the Beaumaris Theatre Inc., a hub for local performing arts.

Beaumaris has also attracted a wide range of creative professionals. Fashion designers including Sally Brown, Linda Jackson, Prue Acton, and Geoff Bade resided in the suburb, alongside architect and historian Mary Turner Shaw and graphic designers Frank Eidlitz and Brian Sadgrove. Ivor William Evans, designer of the Australian flag and canvas goods manufacturer, also called Beaumaris home. Nature writer and journalist Donald Alaster Macdonald, memorialized in the local reserve bearing his name, helped inspire the 1953 formation of the Beaumaris Tree Preservation Society (now Beaumaris Conservation Society), promoting bushland conservation and planting of indigenous vegetation. Musicians such as Colin Hay and siblings Brett and Sally Iggulden, children of Bill Iggulden (designer of the Series K Planet Lamp), founded and performed with The Red Onion Jazz Band in the 1960s.

Notable residents of Beaumaris span the arts, education, design, politics, and public service. These include artists Clarice Beckett, Leonard French, and Arthur and Yvonne Boyd; sculptor Marc Clark; fashion designers Prue Acton and Linda Jackson; journalists Ivor Treharne Birtwistle and Donald Alaster Macdonald; architect and historian Mollie Shaw; musicians Colin Hay and members of The Red Onion Jazz Band; and army general Owen Phillips. Other distinguished residents have included Sir William Fry, politician; Rex Hunt, television personality; Bruce Ruxton, former RSL president; and Len Stretton, judge and Royal Commissioner. Tragic contemporary events, such as the Laos methanol poisoning incident in November 2024, also touched the suburb, with local victims Holly Bowles and Bianca Jones remembered by the community.

Through its theatres, art studios, galleries, and dynamic community of creative professionals, Beaumaris has cultivated a vibrant cultural environment. Its history of performance, innovation, and artistic excellence continues to shape the suburb’s identity as a hub for creativity and heritage in Melbourne’s Bayside.
