Our Team

  • John McMaster


    John has over 30 years experience in the Accounting profession, having commenced work in 1989 while studying his Bachelor of Business (Accountancy) degree – he qualified in 1992 and obtained his Tax Agent Registration in 1993. He has been a member of the Institute of Public Accountants (IPA) since May 1993, and is a Fellow of the Institute.

    Over those 30 years, there have been many changes to how people interact with their Accountant, but John believes a strong relationship with clients is vital to getting the best outcomes.  When he knows you well, he understands what makes you tick, and what things will work for you, your family and your business. Being approachable, honest, and striving to always put his clients first are things that are important to John.

    John is a charter member of the Rotary Club of Woombye Palmwoods and enjoys being able to give back to his community through various activities throughout the year.

    John was born and raised here on the Sunshine Coast, and whilst originally moving away after finishing school to work in several industries, he returned to take up his Accounting studies in 1989.

    He and his wife Jackie met at university, moving permanently back to the Coast in 1992. They have four grown sons and enjoy spending their weekends with friends and family.

  • Ivan de Wet


    Ivan has been working as Taxation Accountant since November 2009, joining the MdW Accountants (formerly McMaster & Associates) team in 2014. Prior to that, Ivan worked for a number of years in rural Queensland where he acquired an appreciation for life in the country and the ups and downs Primary Producers face.

    Ivan accepted an offer of partner in 2021, and together with John, is looking forward to providing clients with the personalised service and support our firm is known for.

    Ivan has owned his own successful business and believes this has assisted him in understanding client needs and the challenges business owners face.

    In other roles Ivan has gained experience in the areas of Financial Management and Human Resources. He enjoys working in the business advisory space and using his own experiences to assist our clients to reach their full business potential.

    Ivan is our SMSF administration leader, which involves liaising with clients and their Financial Advisors to ensure all compliance matters are handled in a timely manner, whilst working together to achieve the best outcomes for clients.

    Ivan’s friendly and dry sense of humour keeps the team on their toes, and he is always up for a bit of office banter.

    Ivan and his wife Natasja, along with their two teenage children enjoy living on the Sunshine Coast, having found their piece of paradise. Outside of work, Ivan enjoys playing golf, stand up paddle boarding, swimming and spending time with his family.

  • Annette Koch


    Annette is the Founder and Principal of Annette Koch Accountants. Annette has over 40 years’ experience working in public practice accounting, of which 36 years has been on the Sunshine Coast. Annette loves the challenge of strategic business planning, with a focus on tax minimisation (not tax evasion) and asset protection.

    Annette enjoys the long-term relationships she has with all her clients, many having Annette as their accountant for a few decades.

    The personal approach Annette takes with every new business client is evident with her “no obligation” guarantee offered in the first meeting. For Annette, it is all about helping her clients (who have different requirements) improve and grow. That has been her motivation in all these years in practice.

    Annette and her husband Robert have 4 sons and, on the weekends, Annette can be busy catching up with their family (including 2 grandsons) and occasionally going fishing with Robert.
