The Bank Bill Swap Rate (BBSW) is Australia’s key short-term interest rate benchmark. It represents the mid-rate for Australian dollar-denominated bank bills (BABs/NCDs) traded in the interbank market. BBSW is used to: Price floating-rate bonds, loans, and securitised products Value interest rate swaps and other derivatives Benchmark bank funding costs and monetary policy transmission

As an actuarial analyst, the report establishes a defensible, data-driven framework to predict claim frequency for a motor portfolio, enabling pricing, underwriting, and portfolio steering decisions to be made with evidence rather than intuition. With assumed Ni∼Poisson(Viλ(Xi)) with exposure Vi​ as an offset and covariates x={weight, distance, age, carage, gender}. The work delivers validated rating relativities for pricing, risk segmentation that underwrites can act on, and an operational High-risk flag with a documented threshold. Together these support tariff setting, portfolio monitoring, fairness checks, and communication with non-technical stakeholders.
