Nexia Australia

Here's a practical breakdown of who Australians actually use for accounting — both firms and software — based on current market info.

🏢 Big Four (large businesses, complex tax/audit needs)

If you run a large company or need audit/assurance work, these are the dominant global names with major Australian operations:

• PwC Australia – offers end-to-end audit and assurance, tax advisory, management consulting, and risk and regulatory solutions, and is the country's largest professional services firm by revenue, employing approximately 8,000 people and generating over AUD $2.6 billion in FY2023 fees.
• EY Australia – headquartered in Sydney, operates as part of the global EY network spanning over 150 countries, with a diverse team of over 8,000 professionals across multiple offices.
• Deloitte – also frequently cited alongside PwC as a leader in applying technology and AI automation in finance, having been at the forefront of adopting ERP systems.
• KPMG rounds out the "Big Four," commonly used by ASX-listed companies and large enterprises.

🏛️ Mid-tier firms (very popular for SMEs and growing businesses)

These are the names most Australian small-to-medium business owners actually deal with day-to-day:

• Pitcher Partners (Melbourne) – a mid-tier firm with a reputation for audit, tax, and advisory services, best suited to well-developed businesses that need solid corporate reporting and specialised advisory.
• RSM Australia – very active nationally, providing tax, audit, risk consulting, and business advisory, with SME and corporate services that make it flexible for long-term financial collaboration.
• Nexia Australia – a network of solutions-focused accountancy and consultancy firms offering a comprehensive, personalised accounting solution.
• Hall Chadwick – a chartered accounting firm offering expert advice across accounting, audit, tax and advisory services.
• BlueRock and Zimsen Partners are also frequently recommended, with Zimsen in particular being one of Australia's leading outsourced accounting firms, backed by a team of 200+ finance professionals who help businesses stay in control of their numbers.

💻 Software Aussies actually use (do-it-yourself or with a bookkeeper)

For day-to-day bookkeeping and BAS/GST, the real market leaders in Australia are:

• Xero – by far the most popular cloud accounting platform with small businesses and their bookkeepers/accountants, largely because most Aussie accounting firms are set up to work directly in it.
• MYOB – the long-standing local (Australian-owned) alternative, still widely used especially among businesses that want strong payroll and compliance features tailored to the ATO.
• QuickBooks Online – popular with sole traders and small businesses, especially those wanting tight integration with invoicing and a lower price point.

🧭 How to actually choose

• Big business / need audit or ASX compliance → Big Four (PwC, EY, Deloitte, KPMG).
• Growing SME needing real advisory → Mid-tier firms like Pitcher Partners, RSM, Nexia, or Hall Chadwick.
• Small business / sole trader wanting a lean setup → A local accountant or bookkeeper running Xero or MYOB, often paired with an outsourced or virtual firm for tax lodgement.
