Cybersecurity and IT Compliance for Perth Accounting Firms in 2026

Accounting firms and financial services businesses in Australia operate under a compliance environment that directly shapes their IT requirements. APRA CPS 234 governs financial services organisations regulated by the Australian Prudential Regulation Authority. ASIC has expectations around operational resilience and data integrity for its licensees. The ATO has specific requirements for tax agents handling client financial data. And the Privacy Act — with significantly strengthened penalties since the 2024 amendments — applies to every firm handling client personal information.

This guide explains the specific IT and cybersecurity requirements for Perth accounting firms and financial services businesses in 2026, what the key regulations actually require from an IT perspective, and how to assess whether your current setup meets the standard.

The regulatory landscape for financial services IT in Australia

APRA CPS 234 — what it means for IT in practice

CPS 234 is the most demanding IT security standard in the Australian financial services sector. While it applies directly to APRA-regulated entities, its influence extends to their suppliers and service providers — meaning accounting firms and financial advisors that provide services to banks, insurers, or superannuation funds may face CPS 234-aligned requirements from their clients.

The core requirements of CPS 234 from an IT perspective include documented information security policy and framework approved at board level, an information asset register identifying all assets and their criticality, systematic testing of controls including penetration testing and vulnerability scanning, incident response capability with defined escalation paths, and notification to APRA of material information security incidents within 72 hours.

The AML/CTF expansion from July 2026

From 1 July 2026, Australia’s anti-money laundering regime expands significantly. The updated AML/CTF Act brings a broader range of professional services — including accounting, legal, and trust and company services — within the reporting entity framework. For accounting firms newly captured by the expanded AML/CTF regime, this means record-keeping systems that can produce the required reports, customer identification and verification records that meet the prescribed standards, and the ability to produce transaction monitoring data if required by AUSTRAC.

The IT controls financial services firms need

Multi-factor authentication — no exceptions

Every account that accesses client financial data — accounting software, client portals, email, cloud storage — needs MFA enforced. Financial services firms are a prime target for business email compromise, where attackers impersonate firm principals or clients to redirect payments or obtain sensitive data.

Privileged access management and segregation of duties

Role-based access controls should mirror your internal segregation of duties — senior accountants, junior staff, administrative personnel, and contractors should have access scoped to what they genuinely need for their role.

Accounting software security

MYOB, Xero, Reckon, and practice management platforms like GreatSoft and Sage HandiSoft are the systems where your most sensitive client data lives. Your IT provider needs to understand how these platforms handle data, what their backup and recovery options are, and how they integrate with Microsoft 365.

Audit logging and evidence trail

CPS 234 and the Privacy Act both require the ability to demonstrate what happened when a security incident occurs. Audit logging needs to be enabled across your key systems — Microsoft 365, accounting software, client portals — and logs need to be retained for a period that meets your regulatory obligations.

Data retention and secure disposal

Tax records have specific retention obligations under the Income Tax Assessment Act — generally five years, with some records longer. Your IT systems need to support retention policies that are enforced technically, not just on paper, and secure disposal processes for data at end of retention.

How financial services firms should approach cybersecurity frameworks

Frequently asked questions

Does APRA CPS 234 apply to my accounting firm?

CPS 234 applies directly to APRA-regulated entities — banks, insurers, superannuation funds, and ADIs. If your accounting firm is not itself APRA-regulated, CPS 234 does not apply directly. However, if you provide services to APRA-regulated entities, they may impose CPS 234-aligned requirements on you as a supplier.

What are the new AML/CTF obligations from July 2026?

From 1 July 2026, the expanded AML/CTF Act captures a broader range of professional services firms including accountants providing certain services. Newly captured firms become reporting entities under the AUSTRAC framework, with obligations including customer due diligence, record-keeping, suspicious matter reporting, and annual compliance reporting. Your IT systems need to support these requirements before the July deadline.

What should I do if a client’s financial data is breached?

Under the Notifiable Data Breaches scheme, you must notify the OAIC and affected individuals if the breach is likely to result in serious harm within 30 days. Contact your IT provider immediately to contain the incident and preserve evidence. Do not delay containment while assessing notification obligations.

How do I securely share financial documents with clients?

Unencrypted email is not appropriate for financial statements, tax returns, or any document containing client financial or personal information. Options include secure client portals built into your practice management software, Microsoft SharePoint with guest access, or encrypted file sharing services. Your IT provider should be able to configure a secure sharing workflow that integrates with your practice management system and Microsoft 365.

How much does managed IT cost for a Perth accounting firm?

For a typical Perth accounting firm, managed IT runs $100–$150 per user per month for fully managed IT with unlimited helpdesk. Adding cybersecurity controls appropriate for financial services brings this to $180–$220 per user per month. See our full IT support pricing guide.
