Corey Trembath


Corey is a proud Transgender Koori man (brotherboy) and a Director in Cloud Advisory at Deloitte. With over 15 years of experience within the ICT industry, he is also volunteers for several LGBTQIA+ and Queer Indigenous charity orgs within the Canberra community and on a national scale, including being Secretary of Wear it Purple.

Corey brings value with his lived experience as an Indigenous and Transgender man and the intersection between those identities. His advocacy journey began shortly after initiating his affirmation journey in 2017, experiencing the gaps in access to essential health care services, adequate policy and protections for Transgender and Gender non-conforming people and a significant lack of visibility and understand in the general population. Most notably, just how difficult it would be for anyone under the age of 18 to access critical health care services without the presence of supportive parents or guardians. With his activism is determined to have an impact on a national scale.

Professionally, Corey brings a wealth of knowledge in ICT and Cyber, as well as in Governance, Risk and Compliance. His work brings about change in the workplace; most noticeable at his previous employer, KPMG Australian, he established internal policy for TGD employees including uplifting entitlements for an increase in affirmation leave from 2 to 6 weeks and the addition of a benefit payment to assist with affirmation costs.
