The imperative for technology in Australian finance
The pace of change keeps rising. Ninety five percent of banking activity is now digital and 2025 brings stricter regulation, fast AI adoption, and growing demand for analytics (Reserve Bank of Australia). Fintech investment has surged, with leaders agreeing that analytics and AI skills are critical to remain competitive (Fintech Week Australia).
Power BI: data driven banking and real time oversight
Power BI for Banking helps teams integrate complex datasets, automate regulatory reporting, and deliver interactive dashboards for executives and front line staff.
- Advanced analytics: DAX and predictive techniques support default forecasting and portfolio stress testing (Sparity overview).
- Fraud detection: Anomaly identification on high volume transactions with alerting to compliance teams.
- Customer insight: Segmentation and product personalisation based on usage and life stage signals.
Banks such as National Australia Bank include Power BI within broader digital transformation to lift reliability and decision speed.
Excel: from reporting backbone to analytics powerhouse
Excel remains essential for modelling, budgeting, reconciliations, and regulatory packs. With Power Query and data visualisation, Excel connects cleanly to Power BI for stronger reporting flows.
- Modelling and forecasting: Three statement, DCF, and scenario models for mergers and risk exposure (Priority Management).
- Automation: Macros, templates, and structured data to reduce errors and manual work.
- Audit and compliance: Consistent layouts for audit ready exports and reconciliations (Perfect Accounting guide).
Microsoft Copilot: AI that speeds finance work
Copilot brings natural language assistance to Excel and Power BI. Teams can summarise reports, draft formulas, reconcile variances, and generate narrative insights for board packs (Copilot for Finance).
- Excel with Copilot: Build complex formulas, summarise balance sheets, and prepare report templates using prompts.
- Power BI with Copilot: Visualise trends, extract insights, and draft commentary for executive packs.
