Antony Syndicate will assess your needs and provide the appropriate experts to get the job done properly, the first time, on time, and on budget.


Registered Tax Agent Sydney

We build long-term taxation relationships with our clients and we wish to share our professionalism and expertise to benefit your business, your family and you.

Bitcoin & Crypto Currency Tax Advisors Sydney

The new age of crypto currency is as exciting as it can be complex. In layman’s terms, crypto currency is simply a virtual currency system, stored in digital wallets.

Forensic Accounting Sydney

The term Forensic simply means that our accountants work to a standard that is suitable for use in Court, providing evidence and expert advice when required.

Outsourced Bookkeeping and Accountancy Operations

We specialise in running the accountancy back office of a majority of our clients, including businesses, superannuation funds, not-for-profits and sporting clubs.

Self-Managed Superannuation

Do you have a self-managed superannuation fund?  The accountancy side of managing these funds can be complex and daunting without qualified help.

Qualified Expert Witness Service

Mark Guest and the Antony Syndicate have presented favourable evidence for clients in a number of major Federal, Supreme, District and Local Court, fraud, business dispute and insolvency cases.


Antony Syndicate has a dedicated division in our Firm that focuses on the needs of our independent female clients – or those wishing they had been financially independent in their past. Essentially accountancy for rich ladies or those wanting to be so.

We say it is simply a fact of life that smart women have the option to leverage their talents and personality to become successful in business, and or to achieve great relationships. That it is always prudent to avoid allowing others to take financial advantage of you.

All businesswomen, (and men!) need a great accountant. A person they can trust, who will maintain privacy, and one that will be there first and foremost, to protect their financial interests.

Perhaps you need financial protection or financial structure guidance in a new or existing relationship.

Other times you might require a forensic accountant to investigate fraud in your business or personal life.

We can provide full-service accounting, tax agent, and business advisory services. Or simply be there from time to time to review financial documents and agreements that you need accounting advice about.

If you need a reliable, smart, and private business adviser, then contact Antony Syndicate soon.
