Joanna Wolthuizen is an Australian abstract painter known for large-scale works that engage architecture through proportion, material stillness, and controlled geometry.
Developed in her Melbourne studio, her practice—termed Composed Abstraction™—positions painting as a spatial instrument rather than an image.
Her works are held in private and corporate collections internationally and are recognised for their structural clarity, enduring presence, and long-term cultural relevance.
