Who I Work With

    Correcting the overlooked.
    Precision where it matters.

    Tax depreciation is one of Australia’s most underutilised areas of tax planning. My work is focused on correcting that.

    Property Investors

    I help investors improve cash flow by aligning depreciation strategy with holding period, financing, and long-term portfolio objectives.

    Business Owners

    I assist businesses in managing rising costs by ensuring construction assets are correctly identified, documented, and depreciated in accordance with legislation.

    Corporate & Institutional

    I advise on complex construction cost allocations and depreciation strategy across large and diverse asset bases, where governance and audit standards are critical.

    How I create a strategic advantage

    I do not approach depreciation as a reporting exercise. I approach it as a decision framework with long-term implications.

    Through CAPAL, Koste.ai's proprietary asset and cost analysis platform, I combine decades of quantity surveying expertise with advanced data modelling to identify and classify construction assets with a level of precision that is often missed by traditional approaches.

    The Result

    Depreciation is integrated into broader financial and tax planning, rather than treated as a one-off compliance task.

    • Legitimate tax depreciation strategies applied.
    • Materially improved after-tax outcomes.
    • Decisions made correctly and documented properly.

    A structured diagnostic for property owners who want to understand whether their asset can be held safely, efficiently, and strategically.

    Most property advice ends at acquisition. The HOLD Review focuses on what happens after—when rising costs, interest rate changes, and policy shifts quietly determine outcomes.
