She toured Australia and the United States doing stage shows, performing at venues that included the Stargazers Convention in Sydney[1](https://www.thefamouspeople.com/profiles/cariba-heine-14534.php).

## Personal life
Heine married chef Matthew Pongrass in June 2024 in an intimate ceremony in Tuscany, and became a mother for the first time in 2025[7](https://los40.com/2025/08/12/de-sirena-de-h2o-a-madre-primeriza-asi-es-la-nueva-vida-de-cariba-heine-quien-dio-vida-a-rikki/). In a 2025 interview she dismissed the idea of an *H2O* reboot, asking whether it would work to see older mermaids[7](https://los40.com/2025/08/12/de-sirena-de-h2o-a-madre-primeriza-asi-es-la-nueva-vida-de-cariba-heine-quien-dio-vida-a-rikki/).
