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 public record firmly places him as Australian, born and raised in Perth. While his surname and given name hint at Italian roots, major databases — including Wikipedia (low confidence) — list his nationality as Australian without detailing ethnicity.

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.
