Ariarne Titmus is one of Australian's greatest Olympians, both on and off the field.

She has dominated the 200m and 400m freestyle events in recent years, but now Ariane is lending her voice to Australian Made Week.

A campaign that celebrates local makers, home-grown products, and the real-world impact of choosing Aussie made.

Ariane Titmus told Peter Fegan on 4BC Breakfast, "If every Australian household just spent $10 more on Australian made products every week, we'd inject $5.6 billion back into the economy and create up to 10,000 jobs and that's just through being a little bit more thoughtful in your shopping."
