Best practices for auditing policy administration systems

Policy administration platforms quietly carry enormous weight inside Australian insurers. They handle new business intake, endorsements, renewals, cancellations, premium allocation across participants, GST accounting, and the hand-off into claims. Many systems in this market have grown through decades of mergers and acquisitions—think of the legacy stacks still running inside merged entities in Sydney and Melbourne, or the consolidated platforms inherited by groups operating across Queensland and Western Australia. Over time, configuration rules, calculation engines, and integration points drift away from the original design, and a disciplined internal audit is often the only mechanism that catches those deviations before they surface as regulator breaches, reconciliation breaks, or customer complaints.

A modern review must also reflect changing expectations from the Australian Prudential Regulation Authority, the operational demands of insureds comparing digital experiences across competitors, and the integration of new technologies such as generative artificial intelligence and machine-readable APIs. The internal audit team that approaches an internal audit of a policy administration system with a current lens is well placed to identify both traditional control gaps and emerging technology risks. The guidance below reflects practices adopted by mature internal audit functions across Australian life and general carriers. Learn more about Sessions.

Set objectives, scope, and stakeholders upfront

The most common cause of a weak audit report on a policy administration system is unclear scope. Auditors sometimes inherit a brief that says "review the policy admin" and assume that means the entire platform. Strong engagements translate the brief into specific objectives: are you reviewing premium calculation accuracy for life participating products, are you testing the integrity of beneficiary data flowing into the claims system, or are you validating access controls around underwriting workflows? Each question points to a different test plan and stakeholder conversation.

Stakeholder mapping matters as much as the test plan. Inside an Australian carrier, the policy administration team often sits within operations rather than IT, which means auditors need to engage both the business owner and the technology custodian. The actuarial function, finance, and risk also need a seat at the table where calculations, financial reporting, or APRA returns rely on outputs from the system. Internal audit should agree objectives with the audit committee in writing, and document any scope limitations with clear reasoning—particularly where a system feeds statutory reporting to APRA or ASIC.

For organisations that already use a risk-based audit universe, the platform should be tagged with a clear risk rating and re-tested on a defined cycle. A high-risk system might warrant annual review, while a stable one might be reviewed every eighteen months. Whatever the cadence, the written scope should call out which products, lines of business, and configuration modules are in scope. New product launches and data migration projects are natural candidates for adding to the scope rather than waiting for the next planned cycle.

Map the system landscape before testing begins

Auditors who jump straight into transaction testing often miss the structural issues that matter most. Effective audits spend meaningful time up front on a system map: what modules exist, how they integrate with the billing engine, the claims platform, and the customer data warehouse, and what external data exchanges connect to the system, such as reinsurance bordereaux or superannuation clearing houses. This map becomes the framework for subsequent walkthroughs and control identification.

System maps frequently reveal hidden dependencies on legacy mainframe screens, third-party aggregators, and outsourced services delivered from offshore hubs. A claims-handling workflow that begins on a customer portal in Adelaide, routes through an offshore business process outsource partner for first notification of loss, and ends at a Sydney office for settlement can quietly bypass controls designed when the entire flow was internal. Mapping those hand-offs is essential, since system and organisation controls reports rarely cover the full chain.

The boundary between the platform and the outside world has become harder to draw. Brokers, comparison websites, and tablet-based service portals increasingly write directly into the system, sometimes through intermediaries that operate in adjacent industries. Audit teams should examine how data captured through such tablet-driven channels flows through validation layers before reaching the policy master file, and whether downstream correction rates tell a story about those entry points.

Identify the key risk areas and controls

The next step is to build a risk and control matrix that captures where things tend to go wrong. Policy administration systems are particularly exposed to configuration errors that miscalculate premiums, apply the wrong rating factors, or skip mandatory regulatory validations.
