The person behind the perspective
The place stayed familiar while the record changed its meaning.
Property information first interested me because a familiar address can conceal several different objects. A building, a leased area, a drawing and a valuation may all refer to the same place while describing different boundaries or moments. I wanted to understand how those records stayed connected as the space changed. That question followed me from spatial analysis into an estate owner, through infrastructure-project information and back into property leadership with a different appreciation of what a reliable record must retain.
I completed spatial-information study at the fictional Alderivane College of Surveying in December 1993 and joined Kelverune Spatial in February 1994. I was an individual contributor in an eight-person group, with no management or expense delegation. The degree did not confer a professional registration claimed in this profile. My work concerned how records identified a place and which source supported the relationship. I learned to be cautious when a shared address or familiar label was treated as proof that two records represented the same thing.
In April 2001 I joined Branvella Estates as property-data lead. By FY 2005–06 I led eighteen colleagues through three direct reports with A$920000 annual function expense. The company’s A$1.4 billion gross property assets and A$92 million rental income were separate context. Working inside the estate owner made me responsible for recurring definitions rather than a single analytical delivery. I became interested in the project information that shaped those records before a property entered ordinary portfolio reporting.
That interest took me to Ternavell Infrastructure in July 2007 as project-information director. The move was a change of employer and problem, not another promotion within Branvella. In 2009 I approved a floor-plan account that treated the latest upload as the latest approved document. Of ninety-six plans reviewed, twenty-eight were subsequently identified as superseded versions. Evan Tarswell’s check against the revision register exposed the assumption. A$480000 supported review and correction, with the approved revision, source and status retained rather than inferred from upload order. I wanted users to see why the selection changed and to retain a route back to the evidence if the revised status was challenged.
I returned to Branvella in September 2014 as head of asset information. The project experience made me more attentive to the difference between a current-looking file and an approved account. In 2017 we examined a building described as 22000 square metres on an external-extent basis and 18000 square metres in its lease schedule. The difference did not prove that 4000 square metres had disappeared. We retained the purpose, basis and version of each account, leaving surveying and leasing owners to confirm the definitions appropriate to their work.
My CDO appointment began in April 2020. I now lead 74 data colleagues through five direct reports with A$12.6 million delegated FY 2026–27 expense. Branvella’s A$7.6 billion gross property assets, A$510 million rental income and 820 employees describe the institution, not my personal investment or leasing authority. Executive board presentations began with this appointment. This fictional record includes no statutory-director seat, and professional valuation, legal and operating decisions remain with their responsible owners.
Recent work has followed the histories hidden by a concise portfolio account. Forty-eight former lease units became ninety-seven current lease areas after reconfiguration; counting both generations would have produced an invented current total. Signed agreements needed to remain distinct from agreements whose commencement had arrived. Valuation records needed their individual dates retained rather than a single portfolio label suggesting that every assessment referred to the same day. The questions are related through the property, but each requires its own evidence and interpretation.
I would bring that perspective to a first board discussion with preparation for responsibilities beyond my executive role. My contribution would be to help colleagues ask what a property measure represents and whether the record still supports the claim made from it. I would also expect the specialist owners to challenge my interpretation. The organisations and decisions here are invented. The narrative shows a career with a departure and return, an owned documentary error and specific reporting choices, so the reader can assess how judgement developed without mistaking a data account for an assurance about buildings, legal rights or investment value.

In my own words
I want a property account to preserve what its record represents. A space can be divided, a lease can begin and a drawing can be superseded without those changes describing the same event. The data function should keep the physical, documentary and commercial histories connected, so that a tidy portfolio view does not erase the evidence needed to understand how the place has changed.
