2003–2015: Home and Away and Hollywood Lucas was involved in drama during her school years and attended courses at the
Victorian College of Arts and
Queensland University of Technology. In 2002, her now agent Sharron Meissner claimed to have discovered Lucas walking on the beach at Port Douglas. In fact, the meeting was arranged well before. Lucas auditioned for the role of
Kit Hunter in
Home and Away; although the producer of the show, Julie McGauran, felt that role was not right for Isabel, she was sufficiently impressed to have a new character, Tasha Andrews, created just for her. and in October of that year appeared on the Australian
Today Show to discuss this topic. In 2008, Lucas moved to
Los Angeles to pursue her acting career further. While working with
Steven Spielberg on the
World War II miniseries,
The Pacific, he suggested Lucas for the role of
Alice in the 2009 film
Transformers: Revenge of the Fallen, sequel to
Transformers (2007), where Spielberg was serving as the series's executive producer. This later became the debut role of Lucas's career, earning her the award for Best Breakout Performance-Female in sci-fi and action at the
2009 Scream Awards. In a much later interview with
Rove, Lucas described the audition process for the role as "very interesting" and drastically different from when she auditioned for other roles prior to
Transformers. She also said that the filming process was a lot different from
Home Away, where she would spend hours shooting various episodes all in one go. In 2008, Lucas was cast in the vampire science-fiction
thriller film Daybreakers and in 2009, she was cast as the character Erica Martin in the remake of the 1984 film
Red Dawn alongside fellow Australian actor
Chris Hemsworth, which was ultimately released in November 2012. In 2009, Lucas played Scarlett in the romantic film
The Waiting City. In 2011, Lucas played the goddess
Athena in the

Give Me Love" by British singer-songwriter
Ed Sheeran. In March 2013, it was announced that Lucas would star in the thriller
Careful What You Wish For, which was released in June 2016. In 2014, Lucas was featured in the documentary
