Wallace-Crabbe was in his early twenties when his paintings caught the attention of the art historian Bernard Smith. Smith described his paintings with: "Lovers of solitary nudes inhabit interiors … the feeling of something held in reserve.". The solitary nude inhabiting interiors is a continuing theme in Wallace-Crabbe's art, in 2004 Wallace-Crabbe explained why:
One of my main pleasures when I'm drawing is talking to the model, just the exchange between two people … I don't want to produce those self-important drawings that once came out of art schools.
Evidence of Wallace-Crabbe conversing with the model is repeated throughout his art practice. In 1996 he received a Creative arts Fellowship at the Australian National University (ANU) where he produced a limited edition book titled Scratchings. The book includes a group of etchings each displaying portraits. Twelve of the thirteen portraits are professors at the ANU, including a portrait of John Passmore, accompanying them is a narrative essay by Wallace-Crabbe describing the conversations he had while talking to each sitter for their portrait. Conversing with the model while drawing is also evident in chapter seven 'In the Shade of Young Maidens' of his autobiography A Man's Childhood (1997). In 2003 a collection of charcoal drawings of his many models was exhibited at the Queen Victoria Building, Sydney, the exhibition was accompanied with a book ‘Conversations and Portraits’ written by himself and including pieces written by some of his models. And in 2004 the publication ‘Studio: Australian Painters on the Nature of Creativity’ Wallace-Crabbe can be seen in his Canberra studio observing and painting the nude model. Art historian and critic, John McDonald, suggests the continuing theme of the nude and the interior has to do with pleasure, rather than conscious art making.
‘[Wallace-Crabbe] thinks of art as a private pleasure. If artists don’t find pleasure in their studios he argues that it is because they are not focused on making art, but on a business called ‘being an artists.’
Rather than ‘being an artist’, as McDonald suggest, Gary Catalano argues that Wallace-Crabbe is in search of the primal psychological aspects of picture making, ‘… Wallace-Crabbe wants to recapture something of the freshness of perception that comes naturally to children when they are first exposed to the external world.’.
Wallace-Crabbe's literary career began in 1978 with the publication of Feral Palit.
"[Feral Palit] was published without any notice at all and then it suddenly got a very good review in ‘The National Times’. Then about three months later Geoffrey Dutton gave it a very good review, mentioning that I think Patrick White and David Campbell had drawn his attention to it."
Patrick White's fondness for Feral Palit formed a correspondence between White and Wallace-Crabbe.Feral Palit (1978) ISBN 978-0732225162

Between 2008 and 2016, Wallace-Crabbe occasionally wrote essays and poems using the name 'Hartmann Wallis'. Finlay Lloyd publishers explain:
Hartmann Wallis, [...] has a wild and somewhat incestuous relationship with the well-known author and artist Robin Wallace-Crabbe.
Through Hartmann, Wallace-Crabbe mused on various reoccurring subjects: art, love/lust, loneliness and animals; usually with a tone of disdain regarding cruelty toward animals and our fellow man. Wallace-Crabbe also composed a short biography (under the name R. C. Brace) for Hartmann. The short biography claims Hartmann spent much of his life living in either Australia, or in an outsider community in remote Northern Canada. Living out the latter yet years of his life in a 'wigwam' on the banks of the Yarra River in Melbourne.
Adam Collier (playwright), of Toronto, composed a monologue titled My friend Rodney. Collier wrote the monologue under the pretence that he and Hartmann had had many conversations. Collier explains:
... I got to know Hartmann while he lived on Parliament Street in Toronto. We would meet most days at a coffee shop, and talk about art, everyday life, and Australian football (what he called ‘footy’). I haven’t spoke to Hartmann since he moved to the Yukon.
Hartmann's poems were describe by Peter Keneally as:
" ...a glorious romp or rant, ranging across history, the minutiae of surburbia, and acerbic view of the literary and artistic world."
Wallace-Crabbe has been involved in the writing, illustrating, designing, and publishing of books for almost fifty years. He designed the cover for the Penguin Publication of R. T. M. Pescott's 'Gardening for Australians' (1965); he also designed books covers for Melbourne University Press (Melbourne) including Vincent Buckley's 'Arcady and Other Places' (1966). Later Wallace-Crabbe collaborated with three presses on the production of limited edition books: 'Elegies: Nine Poems' Brindabella Press (1976); 'Scratchings: a brief account of interloping with a pristine etching plate in hand and other matters' The Edition and Artists Book Studio (1996); and seven titles with Finlay Press (1998-2009).
