Introduction
Few areas of insurance litigation test the outer limits of civil proof more acutely than contested arson claims. Where the very event that is the subject of the dispute consumes most of the available physical evidence, courts are left to draw meaning from conduct, context and character. The Supreme Court of Queensland’s decision in PBR Properties Pty Ltd v Chubb Insurance Australia Limited [2026] QSC 47,1 delivered on 13 March 2026 by Sullivan J, is a compelling study in that exercise. In dismissing a $10 million insurance claim arising from the destruction of a luxury Queensland homestead, the Court found, notwithstanding wholly inconclusive forensic analysis, that the insured’s controlling mind had deliberately lit the fire. The judgment offers significant guidance on the application of the Briginshaw2 principle in civil arson disputes, the methodology for weighing circumstantial evidence, and the probative value of post-loss conduct in evidencing consciousness of guilt.
Background
Wirraway was a high-end rural homestead at Beaudesert, Queensland.3 Originally purchased in November 2012 for approximately $3.575 million, it underwent substantial renovation and expansion between 2012 and 2014, transforming into a complex that included a main homestead, an adjacent ballroom under a shared roof, a guesthouse, a tennis court, a hangar and an upgraded airstrip.4 The property was held by PBR Properties Pty Ltd (‘PBR’) as trustee of the Richardson’s Property Trust. The acquisition and improvement of Wirraway had been funded through a sibling company, Project Gas Services Pty Ltd (‘PGS’), leaving an intercompany loan exceeding $14 million owed by PBR to PGS.5
The persons who sat behind both companies were a married couple: Preston Richardson (‘Mr Richardson’) and Miranda Richardson (‘Mrs Richardson’). Mr Richardson did not survive to see the proceedings conclude as he died by suicide on 11 November 2018, and no relief was pressed against his estate.6 Mrs Richardson had been a party to the proceedings but was later removed.
A policy of insurance (‘the Policy’) had been entered into on 15 May 2016 with a predecessor to Chubb Insurance Australia Limited (‘Chubb’). Subject to its terms, conditions and exclusions, the Policy covered PBR for loss or damage to Wirraway and attached buildings for a sum of $10,024,000 on an extended replacement cost basis, together with a separate contents replacement component.7 The period of insurance ran from 15 May 2016 to 30 June 2017.8 At the relevant time, the property was mortgaged in favour of the National Australia Bank (‘NAB’) as security for a debt of $10,879,734 owed by PGS, and receivers had been appointed to PBR.9
The Fire and the Claim
In the early hours of 28 December 2016, a significant fire swept through Wirraway.10 Mr Richardson was the only person on the property when the emergency call was made.11 Mrs Richardson and the children of the marriage had departed prior to December 2016, and the couple were effectively separated.12
After the fire, PBR lodged a claim under the Policy. Chubb denied indemnity on the basis that the fire had been deliberately lit by Mr Richardson, relying on an exclusion for deliberate or intentional acts. Fire investigation experts were retained by both sides and both experts agreed that the destruction was so extensive that any accelerant, if one had been used, would have left no detectable residue after the blaze.13 Chubb’s case therefore rested entirely upon circumstantial evidence.
Two real issues emerged in the proceedings.14 The first, and determinative, question was whether Mr Richardson had deliberately started the fire. The second which arose only if the first issue resolved in PBR’s favour was concerned with the quantum payable under the Policy, both for the building and for contents.15 A counterclaim brought by Chubb was not pressed at trial; no evidence was led in support of it, and Sullivan J treated it as abandoned.16
The Legal Framework: Briginshaw and the Methodology of Circumstantial Evidence
Sullivan J commenced his analysis by setting out the applicable legal principles with care. Because Chubb sought a finding that would, in substance, constitute the criminal offence of arson, the Briginshaw principle required that such a finding not be made by inexact proofs, indefinite testimony or indirect inferences.17 The onus of proof rested firmly on Chubb as the party asserting the exclusion.18
The Court further adopted the well-established proposition from NRMA Insurance Limited v Collier19 that motive and opportunity (whether in combination or in isolation) are not factors of overwhelming weight in insurance arson litigation. They form part of the overall picture but cannot, standing alone, establish the circumstantial case.
The Court’s Findings
Sullivan J identified a series of findings that, viewed together, produced the requisite inference based on the following:
Financial motive
By the time of the fire, Mr Richardson’s corporate position was acutely precarious. NAB was owed $10,879,734 by PGS.20 Facilities had been extended month by month since mid-2016, with repayment contingent on asset sales that included the sale of Wirraway which wasn’t materialising.21 Sullivan J found that Mr Richardson remained significantly concerned about his personal and corporate financial position at the time of the fire.22 His private communications to Mrs Richardson in December 2016 were those of a man who described himself as having nothing left, urging her to extract as much as possible for their daughters and speaking as though his own future was already over. Critically, by the morning of 28 December 2016, Mr Richardson had formed the view that the cost of rebuilding Wirraway would exceed the total of the Policy coverage. He told his insurance broker that the house was underinsured and that he could not rebuild for $10.5 million. With the realistic sale price for Wirraway at approximately $10 million, the insurance payout represented a marginally superior return without the costs of sale commission and legal fees.23
Sole presence and manufactured opportunity
Mr Richardson was the only person on the property at the time of the fire.24 A prior arrangement had been made for the farm hand, Mr Brook, to stay overnight on 27 December 2016 and one of the few evenings where he had no early milking commitment the following morning and could therefore remain.25 Just before midnight, Mr Richardson directed Mr Brook to return home.26 Sullivan J found that this was contrary to the prior arrangement and that the obvious reason Mr Brook was sent away was that Mr Richardson had by then formed the intention to instigate the fire.27
Consciousness of guilt: the isopropanol text message
In early January 2017, Mr Richardson sent Mrs Richardson a text message asking her to destroy a photograph showing a container of isopropanol so that it would not reach the fire investigator.28 Sullivan J found this conduct to be the functional equivalent of concealing and attempting to destroy evidence. It demonstrated that Mr Richardson believed the investigator did not yet know about the chemical’s presence on the property, and that he actively sought to prevent her from finding out.29 The submission that the isopropanol’s use was already commonly known was rejected: it was Mr Richardson’s own state of mind, and his deliberate act in response to that provided the evidential force.30
The isopropanol as available accelerant
Post-fire communications inconsistent with rebuilding
The video recording
A video recording made by Mr Richardson was tendered as potentially exculpatory material. Sullivan J declined to treat it as such. He reasoned that a recording produced in part for his children to view at a later stage was unlikely to contain a confession, given that such conduct would have diminished him in the eyes of those children. A person characterised as self-centred and narcissistic was unlikely to have been so motivated. The recording was treated as a neutral factor.35
Conclusion and Quantum
Applying the Briginshaw principle at the final stage of his analysis, Sullivan J concluded that the combined force of all the circumstances gave rise to a reasonable and definite inference of arson on the part of Mr Richardson, and that he was satisfied of this to the high degree demanded by that principle.36 The relevant exclusion in the Policy was engaged, and PBR’s claim was dismissed.37
Although quantum did not strictly require determination, Sullivan J nonetheless recorded his conclusions on the figures. Had the claim succeeded, he would have assessed recoverable reconstruction costs at $6,439,262.39 (applying the Rawlinsons methodology, preferred over an actual costs approach due to incomplete information about the original structure), and total contents replacement costs at $198,816.15.38 Both the claim and the counterclaim were formally dismissed by order.39
Implications for Insurance Law and Practice
PBR Properties v Chubb carries several implications of practical significance for property insurers, insured parties and claims professionals.
First, the decision confirms that forensic silence is not fatal to an insurer’s arson defence. The complete absence of physical evidence identifying cause or ignition point does not foreclose a finding of deliberate ignition where the circumstantial case, considered holistically, is sufficiently compelling. Courts will make serious civil findings even where the physical record has been consumed by the very event under scrutiny.
Second, the case reinforces the weight that financial desperation carries as a component of motive — particularly where that desperation is imminent, acute and apparently beyond remedy. The caution endorsed in NRMA v Collier, that motive and opportunity are not overwhelmingly significant factors standing alone, remains good law. But where motive is established with specificity and corroborated by conduct over an extended period, it contributes meaningfully to the holistic assessment.
Third, and perhaps most important for claims practitioners, the judgment underscores the evidential danger of post-loss interference with investigations. Attempts to prevent a fire investigator from receiving potentially relevant material — even a single photograph — can ground a finding of consciousness of guilt. The principle is not confined to outright destruction of evidence; it extends to any deliberate act directed at suppressing information from investigators.
Finally, the case is a reminder that Briginshaw operates as a calibration of the civil standard, not a departure from it. As confirmed in Neat Holdings, it directs attention to the quality of satisfaction required before a serious finding is made, not to any elevation of the underlying standard of proof. Courts applying Briginshaw are not precluded from drawing robust inferences from circumstantial evidence — they are simply required to bring heightened scrutiny to the quality of the evidence before acting upon it.
Conclusion
PBR Properties Pty Ltd v Chubb Insurance Australia Limited [2026] QSC 47 is a significant addition to the body of Queensland insurance jurisprudence. Against a backdrop of complete forensic uncertainty, Sullivan J’s methodical and holistic analysis demonstrates how circumstantial evidence — financial ruin, manufactured solitude, attempted suppression of evidence and post-fire conduct inconsistent with genuine loss — can combine to satisfy even the elevated standard of proof that the Briginshaw principle demands. For insurers, it affirms the viability of circumstantial arson defences in appropriate cases. For those bringing claims, it is a sober reminder that the cumulative weight of conduct, context and character can speak far more loudly than the silence left by the fire itself.
