Although his simple, brightly coloured images of Australian landmarks have adorned a very popular range of clothing and homewares sold under the "Done Design" brand, Done's primary interest is in being a painter.

[2][3] At the end of this decade he travelled abroad and began working with the New York and London based advertising agency J. Walter Thompson.

The company started out by producing small runs of T-shirts featuring Done's art and the garment design of his wife Judy.

Ken Done has long been a supporter of art in Australia especially encouraging school students through awards and sponsorships, although Done decided to sue Australian band TISM for appropriating his work on an album cover.

The album formerly named Australia the Lucky Cunt was released in September 1993 and depicted a Done-style koala with a syringe in its mouth.

[9][10] The album was then re-released in November under the a new title Censored Due to Legal Advice and a new cover depicting four edited pictures depicting Irish singer Sinéad O'Connor on the TV show Saturday Night Live when she tore up a photo of Pope John Paul II.
