Many Trusted Practices
W Advisory has grown by joining forces with established accounting firms whose clients already trusted them. Each practice brought experienced people, proven systems and specialist skills. Together, they give Blacktown clients bookkeeping, tax, SMSF accounting, business advice and wealth planning without juggling several providers.
We don't acquire for size alone. Every firm has to match our standards for accuracy, service and client care, so existing relationships carry on smoothly and every client gains a deeper bench of expertise. For a city as large and varied as Blacktown, that depth makes a real difference.
What Services We Offer
Getting the basics right is where we start, not where we stop. We look ahead, so small issues never become expensive ones.
Bookkeeping & Accounting
Accurate books. Real-time clarity.
W Advisory Blacktown maintains reconciled, ATO-ready records, so you can see your cash position at any moment. Our team handles day-to-day bookkeeping, payroll, BAS and management reports on platforms like Xero, and provides full SMSF accounting services, from recording fund transactions to preparing annual statements, returns and the independent audit file.

Tax Services
Right the first time. Planned all year.
We look after tax for employees, sole traders, companies, trusts and investors. Our registered tax agents prepare and lodge accurate returns, manage BAS, PAYG and FBT obligations, advise ahead of major decisions and put legal tax minimisation strategies in place early, so tax time confirms your plan instead of surprising you.

Financial Planning & Business Advisory
Better structures. Stronger decisions.
Our team helps owners and investors make bigger financial decisions with confidence. We forecast cash flow and test growth plans, weigh up which entity suits your business, work out the smartest ownership for property and shares, and build wealth and succession plans that support your family's long-term goals.

Payday Super Services
Every pay run. Every fund. On time.
Since Payday Super began on 1 July 2026, every pay run triggers a contribution, based on qualifying earnings, that must reach the employee's fund within 7 business days. W Advisory Blacktown configures your payroll and clearing, checks contractor arrangements and reconciles contributions after each pay run, so you avoid the super guarantee charge.
Learn MoreHow We Started
William Wong started W Advisory in 2012 because too many business owners were getting advice that was late, vague or hard to act on. His answer was a firm built on clear, proactive guidance. That principle still drives a network that now spans New South Wales, and W Advisory Blacktown brings it to the heart of Western Sydney.
The network grew by welcoming established practices, each adding people, systems and specialist knowledge. For Blacktown clients, the result is a single team for bookkeeping, tax, structuring, SMSF accounting and long-term wealth planning.
Qualified professionals lead every engagement. Chartered Accountants and registered tax agents handle today's deadlines and, just as importantly, the decisions that will shape your position five or ten years out.
Blacktown is the largest council area in New South Wales by population and one of its most culturally diverse, with established neighbourhoods like Seven Hills and Mount Druitt alongside fast-growing estates in Marsden Park, Schofields and Riverstone. Its industrial parks at Arndell Park, Huntingwood, Minchinbury and Glendenning form one of Sydney's biggest transport and logistics hubs, while healthcare and retail employ thousands more. Each brings its own financial pressures: owner-drivers and fleet operators managing fuel costs and contractor super, healthcare practices growing their teams, family businesses planning succession across generations, and investors balancing older rentals with new-build purchases. Our advice is shaped around those realities.
We aim to be the firm Blacktown businesses and families trust for honest numbers, practical advice and wealth that lasts beyond one generation.

Frequently
Asked
Questions
(FAQs)
1. Why choose a local accountant in Blacktown?
A local accountant in Blacktown understands the businesses that drive Western Sydney, from logistics and transport operators to healthcare practices, retailers, tradies and family-run businesses, along with the tax issues each one faces. W Advisory Blacktown combines that local knowledge with ATO expertise, so your advice reflects how your industry actually operates.
2. Where is your office, and which suburbs do you cover?
W Advisory Blacktown is based at 2 Reservoir Road, Blacktown, and works with clients across the Blacktown local government area, including Seven Hills, Mount Druitt, Doonside, Rouse Hill, Marsden Park, Schofields and Riverstone. You can meet us in person, or book a phone or video consultation if that suits your schedule better.
3. Can you help rideshare drivers, owner-drivers and transport operators?
Our team helps rideshare drivers, owner-drivers and transport businesses with GST, BAS, vehicle expenses, fuel tax credits and contractor super. Rideshare drivers must register for GST from their first fare, regardless of turnover, and heavy vehicle operators may be eligible for fuel tax credits. We make sure you claim your entitlements and stay compliant.
4. Do you offer bookkeeping and tax services together?
Yes. We offer bookkeeping, BAS and tax services through one team, so the people keeping your records are the same people preparing your returns. That removes handovers between separate providers, catches errors earlier and gives you one clear, consistent view of your business and personal finances throughout the year.
5. Are your accountants qualified and registered?
Every W Advisory Blacktown client is looked after by qualified professionals: Chartered Accountants, CPA Australia members and tax agents registered with the Tax Practitioners Board. To stay registered, tax agents must hold approved qualifications, show relevant experience and complete continuing education each year, giving you confidence in every return we lodge.
6. Which industries do you work with in Blacktown?
We work with transport and logistics operators, healthcare and allied health practices, tradies and construction businesses, retail and hospitality owners, multicultural family businesses, property investors, SMSF trustees and professionals. Whatever the industry, clients come to us for reliable lodgements and advice that helps the business, and the family behind it, move forward.
7. How do I get started with W Advisory Blacktown?
Getting started with W Advisory Blacktown begins with a free consultation, in person at our Blacktown office or by phone or video. An accountant reviews your current position, highlights gaps or missed opportunities and recommends a clear plan, including what it will cost, before any work begins.
