On 1 November 2013, Jackie and co-host Kyle Sandilands announced they would not be returning in 2014 to host their 2Day FM breakfast show, which at that time was generating around 30 million AUD in advertising revenue yearly.

[3] In 2018, Sandilands dared Jackie O to write and record a song in one day; the result, "Honey Money", written by Avalonia and produced by KIIS FM producer Kian Oliver (who also provided a rap), went to number one on the Australian iTunes chart (#13 on the ARIA Digital Sales chart, spending one week within the Top 50), with all proceeds being donated to Drought Angels, a charity set up to help drought-affected Australian farmers.

In October 2007, she along with her radio partner Kyle Sandilands would take Gretel Killeen's job in hosting the 2008 series of Big Brother Australia.

In 2019, it was announced that Jackie O would be one of the panellists on The Masked Singer Australia alongside Dannii Minogue, Dave Hughes and Lindsay Lohan.

[16] In 2009, Jackie O was named as the second most hated celebrity in an annual list by Zoo Magazine, sharing the top two with her radio co-host.

In late 2019, she revealed that she had begun to drastically put on weight and was desperate to shed it back off before filming the second season of The Masked Singer.
