Collette Dinnigan made her name as an international fashion designer, but she’s making a fortune by flipping high-end property.

In the two years since Dinnigan turned her designer eye to interiors, she has bought and sold more than $33 million worth of luxury weekender and Sydney real estate, the most recent of which is the sale of her Southern Highlands home Springfield Farm for $7.25 million – 18 months after she bought it.
