About

Rudi van der
Westhuizen CA

Chartered Accountant. Commercial strategist. The CFO who's been through it — and can help you navigate it too.

Career Overview

I don't sell time — I deliver outcomes

Chartered Accountant with 20+ years of senior financial leadership across Deloitte, Optus, Swissport, and Parratech. With a career spanning audit, advisory, commercial finance, FP&A, and CFO-level operations, I have a rare breadth of technical accounting depth combined with sharp commercial instincts.

My value proposition is built on translating complex financial data into clear business decisions — for boards, executives, and operators alike. I've owned P&Ls up to $1BN, led multi-disciplinary teams, and delivered meaningful cost reductions, revenue growth, and efficiency gains across highly competitive environments.

I am focused on bringing that enterprise-grade financial rigour to small and mid-sized businesses — particularly those in the telecommunications and technology services sector — where my Optus channel finance and commercial management background is directly transferable.
