You’re not making the most of your money — and it’s not your fault.
Why this happens:
Box-ticking compliance firms
Only complete tax returns and reports.
No real advice on business growth or financial planning.
Treat every client the same, no personalised strategy.
Risky loophole spruikers
Push “quick fixes” and tax dodges that create long-term risks.
Focus on hype, not sustainable financial health.
Leave you vulnerable to audits and penalties.
Slow, reactive service
Advice arrives after deadlines have passed.
Issues are fixed only when problems already exist.
No forward-looking guidance to help you grow.
B.W. Sims & Co. approach is different:
Strategic
We go beyond compliance — helping you plan for growth, wealth, and financial security.
Tailored strategies that fit your goals, not generic solutions.
Regular reviews to keep you ahead, not behind.
Ethical
Transparent, trustworthy advice with no gimmicks.
We keep you compliant while maximising opportunities.
A long-term partner you can rely on.
Proactive
We identify risks and opportunities before they impact you.
Timely communication and updates so you’re never in the dark.
Continuous support to make sure your money is always working harder for you.
We’re the Trusted Operator in the Grey
Strategic, legal, but maximised positioning
We help clients navigate the complex space between aggressive loopholes and conservative compliance. Our approach is strategic, legal, and optimised — giving you the maximum benefit without the unnecessary risk.
Strategic over Standard
Go beyond basic compliance to actively structure, plan, and optimise your financial outcomes.
Ethical over Excessive
No risky loopholes, no hype-driven shortcuts.
Transparent over Trendy
Clear, plain-language communication. No hidden agendas, no unnecessary complexity.

Brian has been my trusted accountant and friend for more than 15 years. Over that time, he has saved us more than $1.0M in income taxes through his vast knowledge and experience of the Australian taxation and superannuation system. My wife and I run our own private consultancy business which Brian has helped us build and grow over the years. His advice has been second to none. Brian is always available when you need him and is always friendly and courteous. I would gladly recommend him to anyone looking to start a new business venture as he'll help set it just right or to those wanting to simply save more on their income taxes. Well done Brian and thank you for so much for all those years of great service and advice.

We have recently changed accountant to B.W. Sims and Co. The bloodhounds have saved us a lot of tax and will sniff out every legal cent you can save. Easy to talk to and very prompt with replies and correspondence. I am recommending Brian to everyone.
Brian Sims has been accountant to me and my husband for almost 20 years now. We have always found him easy to deal with, attentive and proactive and that is why we have stayed with him for so long. He attends to our affairs with extreme care and has always lodged our tax returns on time, guiding us carefully with any queries we might have and streamlining the process for us with a minimum of fuss. We can say without any hesitation at all that we would highly recommend Brian to any potential client. He has every client's best interests at heart and maintains a calm and reassuring disposition during the entire process, instilling confidence in his judgements.
We have been in the air conditioning and refrigeration business for over 25 years and employ over 40 staff. Brian has saved us thousands in tax over the past 12 or more years. We have found him to be fast, efficient and easy to get along with. Brian helps not only with tax , but finance applications, business structure advice, purchase and sale of business advice and accounting investigations where necessary. We would have no hesitation in recommending Brian to any potential client who may need his services.
