Limestone Group is an Australian professional development consultancy delivering evidence-based programs that satisfy CPD requirements across legal, accounting, health, engineering, and teaching professions, as well as industry leaders seeking self-directed development.
Every program is designed to produce genuine, lasting behaviour change, not just hours logged. Grounded in psychology and built around the real challenges each discipline faces, all programs are audit-ready and recognised across CPA Australia, CA ANZ, IPA, AHPRA, Engineers Australia, NESA, VIT, and state registration boards.
Our programs are designed and facilitated by Suzanne (Sues) Tonks, Managing Director and one of Australia's most experienced practitioners at the intersection of psychology, executive leadership, and strategic communication. With more than 20 years of senior practice and postgraduate psychology qualifications, she has worked across C-suite executive development, corporate strategy, government, not-for-profit, and global brands at the highest level of decision-making. Sues is the developer of the AIMPI (AI Management Personality Inventory) and a sought-after speaker on leadership, AI, and psychology in professional practice.
