What ethnicity is Jack Della Maddalena?
- Born in Perth, Western Australia – UFC.com (official athlete profile)
- Described as an Australian professional mixed martial artist – UFC.com
- His full name Giacomo ‘Jack’ Della Maddalena suggests Italian heritage, but no reliable source has confirmed his ethnic background.

The implication: For now, the most accurate description is that Della Maddalena is an Australian fighter of likely Italian descent, but the lack of a primary source means that detail remains officially unconfirmed.
