Early life and education
Mortlock and her family traveled around Australia via camper trailer when she was 9 years old. She was homeschooled together with her two younger. They settled in Jerilderie soon after.

In September 2018, she graduated from Finley High School in Finley, New South Wales. She eventually entered the University of Wollongong in Wollongong, New South Wales to obtain double bachelor's degrees in global sustainability and politics.

Miss Earth 2022
By winning Miss Earth Australia 2022, Mortlock was tasked to have advocacy as one of the core requirements for joining Miss Earth. Her advocacy was Action, Care, and Education (ACE). Mortlock added, "Climate change and environmental protection are all linked through webs of connection. If we change one element of the ecosystem, then it will ripple out to others. This is why we must use the pillars of ACE to make the most effective changes. Only through Caring about our environment, Educating ourselves on current environmental changes, and then taking direct Action will we be able to protect Mother Earth."

The main theme of Miss Earth 2022 was ME Loves Fauna, and candidates were required to promote a creature from their country; Mortlock chose the Swift parrot. She said that according to reports, there are only 750 left which makes it a critically endangered species. She cited the habitat loss in Tasmania, which is the Swift parrots' breeding grounds, as the main reason this.

Mortlock competed with 85 other entries at Miss Earth 2022.

During the course of the preliminary events, she won the following awards:
 * Darling of the Press (Asia & Oceania)
 * Swimsuit Competition (Asia & Oceania)
 * Beach Wear Competition (Fire Group)
 * Miss Congeniality

Mortlock won Miss Earth – Air 2022, and South Korea's Mina Sue Choi won Miss Earth 2022.
