Di Winkler senses she is on the verge of a breakthrough with her Summer Foundation, which was set up to find accommodation for younger people with disabilities, many of whom are being housed in aged-care facilities.

Winkler is married to BRW Rich List member and MYOB founder and Xero investor Craig Winkler, whose wealth was quoted at $363 million in the 2016 Rich List. The judging panel chose the Winklers as BOSS True Leaders 2016 for their philanthropy. Di Winkler is a former occupational therapist for people with severe brain injuries. Craig Winkler declined to be interviewed but Di Winkler was eager to talk about the foundation she started in 2006.
