How to prepare for an IFRS 16 lease accounting audit: a complete checklist
Preparing for an IFRS 16 audit? This complete checklist covers what auditors look for, the most common deficiencies, and how to build an audit-ready...
LOIS is purpose-built lease accounting and management software for Australian mining, energy, and resources companies - handling AASB 16 compliance, fleet bulk uploads, and audit-ready reporting in one platform.
Mining and energy companies manage some of the most complex lease portfolios in any industry - heavy equipment fleets, remote site infrastructure, mobile assets, and corporate property all on a single balance sheet under AASB 16. LOIS was built to handle exactly this complexity, and currently manages over AUD 54 billion in leased assets for clients in resources, energy, and related sectors.
The platform brings lease accounting, fleet management, and property management together in a single, unified system - so finance teams at mining and energy companies get full AASB 16 compliance, automated bulk fleet uploads, complete audit trails, and a single source of truth across every asset class. Updated April 2026.
Mining and energy lease portfolios sit in a different category to almost any other industry. These five challenges come up in nearly every conversation we have with finance teams at mining and energy operators - the ones managing large, multi-jurisdictional portfolios where a general-purpose tool or spreadsheet simply cannot keep up.
Large-volume fleet uploads from multiple equipment providers
Mining and energy operators lease fleets of hundreds - sometimes thousands - of items: drills, trucks, excavators, light vehicles, mobile plant. Each provider sends data in a different format. Reformatting and loading that manually every month is a real operational risk, and it eats into time your finance team could spend on higher-value work.
CPI and market-linked adjustments across hundreds of leases simultaneously
Resources leases commonly carry CPI escalation clauses, market rent reviews, and price adjustments tied to commodity indices. Getting every adjustment right across a large portfolio - and making sure it flows through correctly to the right-of-use asset and lease liability - is exactly the kind of work that creates errors when it is done manually.
Remote site complexity across multiple jurisdictions
Operations spread across multiple states - and sometimes multiple countries - bring different currencies, tax treatments, and operational periods into the same portfolio. That diversity needs to sit inside one platform. Managing it through parallel spreadsheets or separate systems is how discrepancies get missed.
AASB 16 compliance for both property and equipment on a single platform
Most tools handle property or fleet reasonably well, but few handle both with equal rigour. A remote site office lease and a fleet of drilling equipment need the same careful treatment: right-of-use assets, lease liabilities, amortisation, and depreciation calculated correctly for each asset class, inside the same system.
Audit readiness for listed companies under ASIC scrutiny
For ASX-listed mining and energy companies, lease accounting sits on the balance sheet as a material item. External auditors and ASIC look at it closely. A single unresolved discrepancy in the audit file can extend the review process and delay sign-off. The evidence standard is higher than most spreadsheet-based processes can realistically meet.
Each capability in LOIS is built around the specific accounting and operational demands of complex, asset-heavy portfolios - not retrofitted from a general property tool. Here is how it maps to the five challenges above.
Fleet Management module - automated bulk uploads from any provider format
The LOIS Fleet Management module is built for organisations that receive large lease data files from multiple external providers each month. Upload data in any standard format - LOIS handles the field mapping once and runs consistently from there. No manual reformatting, no provider-by-provider workarounds. For mining companies managing fleets across multiple equipment suppliers, this removes a meaningful chunk of the monthly burden from the finance team.
Automated validation - catching discrepancies before they reach the balance sheet
Every upload is automatically cross-checked against your existing LOIS data before any changes are applied. LOIS identifies new leases, price changes, CPI adjustments, extensions, scope reductions, and terminations as distinct categories - each with its own accounting treatment. Discrepancies surface at upload, not at audit. That validation step is the control point manual processes lack, and it is what makes the monthly process reliable when you are managing hundreds of leases.
IFRS 16 and AASB 16 automation across income statement, cash flow, and balance sheet
LOIS automates the full AASB 16 calculation lifecycle: right-of-use assets, lease liabilities, amortisation schedules, depreciation, interest expense, and disclosure notes. Every lease modification triggers an automatic remeasurement. Journals are generated and mapped to your general ledger, ready to post directly to your ERP. Property and equipment leases sit inside the same system, producing consistent, reconciled outputs across both asset classes at month-end.
Single platform for property, fleet, and asset management
LOIS brings property, fleet, and asset management together in one system, so the data driving your lease accounting is the same data property and operations teams use for milestones, expiries, and site-level decisions. There are no manual handoffs between systems, and no reconciliation between a property tool and an accounting tool. For mining and energy companies with operations spread across multiple sites, this eliminates the data gaps that typically open up between head office finance and site-level teams.
Full audit trail for every modification - built for external auditor scrutiny
Every change to every lease in LOIS is captured automatically with a complete, timestamped audit trail. For listed mining and energy companies, that means your finance team can answer auditor questions with specific, documented evidence - rather than reconstructing a calculation history from a spreadsheet. The trail covers every modification, reassessment, extension, and termination in the format auditors expect. See our IFRS 16 audit preparation checklist for more on what auditors typically look for.

LOIS is built and supported by CA-qualified lease accounting experts. When your finance team has a question about how a scope reduction should be treated under AASB 16, you get an answer from a leasing specialist who has dealt with that exact situation before - not a ticket response and not a link to a help article. That depth of expertise runs through the platform itself: every calculation, workflow, and audit output is designed by people who know what a listed mining company's auditors will ask for.
For ASX-listed mining and energy companies, AASB 16 is not a compliance checkbox - it is a material financial reporting obligation that directly affects the balance sheet, debt covenants, and key financial ratios. The quality of the underlying lease data and the controls around it become a genuine audit risk when the numbers are large enough to move the balance sheet.
Audit scrutiny in practice
ASIC has consistently identified lease accounting as an area requiring particular attention in financial reports. For listed companies, a material misstatement in right-of-use assets or lease liabilities can require restatement, trigger shareholder questions, and attract regulatory review. LOIS's full audit trail, automated reconciliation, and CA-qualified expert support are designed specifically to meet this standard.

Book a demoWhat lease accounting software do mining companies use?
Mining companies in Australia operating under AASB 16 use dedicated lease accounting platforms to manage the volume and complexity of their portfolios. LOIS is used by a number of ASX-listed and private mining and resources companies, including South32, MMG, Evolution Mining, and Aurelia Metals. The platform is designed for high-volume fleet environments as well as multi-site property portfolios, and handles both asset classes within a single system. Other dedicated lease accounting platforms are used in the sector, though none offer the same combination of fleet upload automation, property management, and CA-qualified expert support in a single platform.
Can LOIS handle bulk fleet lease uploads for mining equipment?
Yes. The LOIS Fleet Management module is built for organisations that receive large lease datasets from multiple equipment providers each month, each in a different format. LOIS accepts data in any standard format, handles the field mapping, cross-checks incoming data against your existing records, and identifies all change types - new leases, price changes, CPI adjustments, extensions, scope reductions, and terminations - before applying any updates. That removes the manual reformatting and data loading burden that mining finance teams typically carry when managing fleet lease data across multiple providers.
How does LOIS support AASB 16 compliance for listed mining companies?
LOIS automates the full AASB 16 calculation lifecycle: right-of-use asset recognition, lease liability measurement, amortisation, depreciation, interest expense, and disclosure note preparation. Every lease modification triggers an automatic remeasurement and is captured in a complete, timestamped audit trail. For listed mining companies, LOIS also provides general ledger integration so journals are ready to post directly to the ERP, and a managed service option where CA-qualified LOIS experts own the monthly calculation and reporting process end-to-end. This combination of automation, audit trail, and expert support is built for the standard that external auditors and ASIC apply to listed company financial reports.
Does LOIS handle multiple currencies for remote site leases?
LOIS is designed to handle the multi-jurisdictional complexity of mining and energy portfolios, including leases denominated in different currencies across remote sites in different countries. Mining and energy companies with operations spanning Australia, Papua New Guinea, or other jurisdictions can manage all lease data within a single LOIS instance. Speak to a LOIS specialist about your specific currency and jurisdiction requirements when booking a demonstration.
