Most businesses see Assurance & Audits as an inevitable part of the year but rarely embrace them.
The team at Sinclair Wilson regards business Assurance & Audits as an opportunity for greater efficiencies, improved systems and better reporting.
We see statutory Auditing as the starting point. We are well-equipped to analyse every aspect of a business from management through to systems structure and potential. All with a view to making your business or organisation stronger in the areas of finance, governance and accountability.
Sinclair Wilson’s Assurance & Audit Division comprises two core areas, being the completion of Statutory Audits and the involvement in Management and System Reviews. To this end we take both a traditional and non-traditional or value-added approach to Auditing.

Our audit services uncover opportunities to improve performance, streamline operations and reinforce trust in your financial reporting.

- Government-Funded Service Organisations.
In providing meaningful service to clients, we seek to provide value-added benefits which include a focus on feedback in deficiencies identified and, more importantly, recommendation for change in order to enhance organisations’ systems, procedures and human effectiveness. Our main focus with Statutory Audit clients is to undertake the regulatory and legislative requirements of completing the Audit and consequently providing the client with recommendations to improve their financial control procedures, financial performance and aspects of their record keeping.
Internal audit and forensic reviews comprise the assessment of an organisation’s:
- Structure
- Internal Controls
- Systems
- Procedures.
It is often beneficial for a professional external to the organisation to review these aspects and offer positive and practical changes to your organisation’s financial and administrative processes. We are able to undertake our review for the organisation as a whole or on a modular basis such as receivables, purchasing, sales, administration, fixed asset control or payroll.
Sinclair Wilson’s Assurance & Audit Division is also responsible for the Audit of more than 400 self-managed Australian Tax Office regulated superannuation funds. In undertaking these Audits, specific reference is made to the compliance and fund responsibilities to be adhered to by the trustees of the superannuation funds.
