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 are more complex than any general-purpose tool or spreadsheet can reliably manage. These five challenges come up consistently when talking to finance teams at mining and energy operators dealing with large, multi-jurisdictional portfolios under AASB 16.
Mining and energy operators lease fleets of hundreds or thousands of items - drills, trucks, excavators, light vehicles, and mobile equipment - from multiple providers who each use different data formats. Reformatting and loading that data manually every month is a significant operational risk and a drain on finance team time.
Resources leases commonly include CPI escalation clauses, market rent reviews, and price adjustments tied to commodity indices. Applying these correctly and consistently across a large portfolio - and ensuring every adjustment flows through to the right-of-use asset and lease liability calculations - is error-prone when done manually.
Mining and energy operations span remote sites across multiple states and sometimes multiple countries, introducing different currencies, tax treatments, and operational periods into the same lease portfolio. A single platform needs to handle this diversity without forcing the finance team to manage it through parallel spreadsheets or separate systems.
Most tools handle either property or fleet reasonably well, but not both. Mining and energy companies need a platform that treats a remote site office lease and a fleet of drilling equipment with equal rigour - calculating right-of-use assets, lease liabilities, amortisation, and depreciation correctly for both asset classes within a single system.
For ASX-listed mining and energy companies, lease accounting is a material balance sheet item that external auditors and ASIC will scrutinise closely. A single unresolved discrepancy in the audit file can trigger extended review processes and delay sign-off. The standard for evidence is higher than most spreadsheet-based processes can meet.
LOIS maps its platform capabilities directly to the five problems above. Each module is built around the specific accounting and operational demands of complex, asset-heavy portfolios, not retrofitted from a general property tool.
The LOIS Fleet Management module is built specifically for organisations that receive large lease data files from multiple external providers each month. Upload data in any standard format - LOIS handles the 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 alone removes a significant monthly burden from the finance team.
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. This validation layer is the critical control point that manual processes lack entirely, and it is what makes the monthly process reliable at scale.
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. The platform handles property and equipment leases within the same system, producing consistent, reconciled outputs across both asset classes at month-end.
LOIS brings property, fleet, and asset management together in one unified system, so the data that drives lease accounting is the same data that property and operations teams use to manage milestones, expiries, and site-level decisions. No manual handoffs between systems. No reconciliation between a property tool and an accounting tool. One source of truth for finance, property, and operations. For mining and energy companies with geographically dispersed operations, this integration eliminates the data silos that typically emerge between head office finance and site-level teams.
Every change to every lease in LOIS is captured automatically with a complete, timestamped audit trail. For listed mining and energy companies, this means finance teams can respond to 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 form auditors expect. Learn more about what auditors look for in our IFRS 16 audit preparation checklist.
LOIS provides eight core capabilities that cover the full lease lifecycle for resources-sector finance teams: from automated AASB 16 calculations and bulk fleet uploads through to managed service delivery for teams that prefer expert-led monthly processing. As of April 2026:
LOIS clients in the mining and resources sector include South32, MMG, Evolution Mining, and Aurelia Metals: organisations managing large, complex lease portfolios spanning multiple sites, asset classes, and jurisdictions under AASB 16 and IFRS 16.

LOIS is built and supported by CA-qualified lease accounting experts, not a generic software helpdesk. When a mining company's finance team has a question about how a scope reduction should be treated under AASB 16, they get an answer from a leasing specialist who has dealt with that exact situation before, not a ticket response. This depth of expertise is reflected in the platform itself: every calculation, workflow, and audit output is designed around how the standard actually works in practice for complex, asset-heavy organisations.

ASX-listed mining and energy companies face a level of regulatory exposure that privately-held organisations do not face to the same degree. ASIC actively monitors IFRS 16 and AASB 16 disclosures as part of its financial reporting surveillance program. Lease liabilities are a material line item on most mining company balance sheets, often in the hundreds of millions of dollars. A material misstatement - even one caused by a process failure rather than intent - creates real risk: auditor qualification, restatement, and regulatory attention.
LOIS provides the controls that listed mining companies need to manage that risk. The full audit trail means every balance sheet figure can be traced back to its source. The automated validation process means discrepancies are caught before journals are posted, not after. The CA-qualified support team means the platform is applied correctly for the specific circumstances of each client. For CFOs and financial controllers at listed mining companies, LOIS removes lease accounting as a source of audit risk and makes it a controlled, repeatable monthly process.
For teams that want to outsource the process entirely, the LOIS Managed Service provides expert validation, calculation, and audit-ready monthly reporting delivered by LOIS's own CA-qualified team.

LOIS clients in the mining and resources sector include South32, MMG, Evolution Mining, and Aurelia Metals. The platform is designed to handle the specific demands of mining portfolios: large fleet volumes from multiple providers, remote site property leases, multi-jurisdictional structures, and the audit-readiness requirements of ASX-listed companies. General tools such as MRI Software are also used, though they are not purpose-built for the volume and data flow characteristics of mining lease portfolios.
Yes. The LOIS Fleet Management module is built specifically for large-volume lease data flows from external providers. It accepts data in any standard format - so if you receive monthly files from multiple equipment suppliers in different formats, LOIS handles the mapping and processing without requiring your finance team to manually reformat each file. Every upload is automatically cross-checked against your existing portfolio to identify new leases, price changes, CPI adjustments, extensions, scope reductions, and terminations before any changes are applied to live records.
LOIS automates the full AASB 16 calculation process: right-of-use assets, lease liabilities, amortisation, depreciation, interest expense, and disclosure notes across both property and equipment leases in a single platform. For ASX-listed mining companies, LOIS provides a complete audit trail for every lease modification, so external auditors can trace any balance sheet figure back to its source. The platform is built and supported by CA-qualified lease accounting experts who understand how AASB 16 applies to complex, asset-heavy portfolios in practice, reducing the risk of material misstatements that would attract ASIC attention.
LOIS is designed for organisations managing complex, multi-jurisdictional lease portfolios, including mining and energy companies with operations across multiple countries where leases may be denominated in different currencies. The platform accommodates the diversity of asset types, currencies, and operational structures that characterise large resources-sector portfolios. For specific requirements around currency configuration or cross-border lease structures, the LOIS team - made up of CA-qualified lease accounting specialists - can advise on setup and ongoing management.
