Does debt recycling actually build wealth?

Debt recycling replaces paid-down non-deductible home loan debt with tax-deductible investment loan debt, so the same dollars do two jobs: pay off the mortgage faster and buy income-producing shares. Interest on the investment portion is tax-deductible (ATO: interest is deductible when the borrowed money produces assessable income such as dividends); interest on the home loan is not. The split-loan structure is legal provided the two loan accounts stay separate. Source: ATO; Australian Securities & Investments Commission.

Worked example. $500,000 mortgage at 6%, 25 years. Extra $1,000/month debt-recycled (paid to home loan, redrawn into an investment split and put into shares at 8% total return, 4% franked yield, 37% marginal tax). Year-1 interest on the investment split ≈ $720 → $266 tax deduction. Over 25 years the portfolio builds an extra $100,000+ vs just paying down the mortgage with the same $1,000/month. Works best at 30%+ marginal tax, stable income, 10+ year horizon. Key risks: share market drawdowns, rate rises, job loss — you're servicing two loans.
