Making the complex clear and strategic.


Defendi Communications was founded on a passion for thoroughly understanding and appreciating the technical, corporate, and academic; the desire to make it clear and accessible; and to strategically enable its objectives.

I bring over 19 years’ experience as a proven business communicator.

I have worked both nationally and abroad for a range of companies – from boutique start-ups through to multinational mining and engineering service providers. Combined, these experiences have provided me with an agile skill set, a tested understanding of best practice, and the capacity to deliver creative solutions.

What I create is clear, strategically-positioned and shines in a competitive environment.


Copywriting and editing

I partner with clients to unravel complex concepts, and present their messages clearly and accurately. Services include:

Competitive tenders



Website copy

Social media copy

Media releases

Strategic communications and documents

From an editing standpoint, services range from a simple edit or proof of your current material,  through to a full structural and analytical assessment.


I have the expertise to provide the winning strategy, project coordination and effective wording needed to win competitive bids, proposals and grants. 

Advisory services extend to calculated and refined messaging for a variety of communication platforms. 

Services also include a full audit of your current documents and communication platforms; to ascertain where messaging gaps lay, and develop a new strategy that performs and evolves with you.
