She emerged from the waves looking relaxed and refreshed before towelling herself down on the shore. 

The mother of five shares four children with her late ex-husband Angus Hawley – Lucia, 26, Hamish, 23, James, 24, and Sybella, 16.

The former couple were married for 11 years but split in 2007.

In April 2015, Angus died in New York from a suspected heart attack at the age of 46.

After their separation, Antonia married Singaporean-based businessman Craig Marran in April 2010.

Antonia and her family recently moved back to Sydney, after almost a decade of living in Singapore.

She said in 2017 that balancing six children with a busy career can be difficult. 

‘There really is no secret. No matter how many kids you have, it’s tricky,’ she told 9Honey of motherhood.
