Giving up a plumbing apprenticeship at 17 years old paid off for Jacobz: after appearing in several commercials and guest roles he landed his first full time acting gig as Zac Croft in Heartbreak High.
After wrapping up his role in Heartbreak High, Luke became a jack-of-all-trades, working in a cafe, retail and also the hospitality industry. Taking his love of travel and meeting people he also managed a youth hostel. In August 2000 he travelled extensively through Europe and the United Kingdom.
Having the gift of the gab scored him a job as a promotional representative for the Pepsi Taste Challenge campaign in the summer of 1999-2000 and led him to the hosting role on Channels Seven's children show The Big Arvo.
In 2004, Luke hosted the popular Popstars program and co-hosted Iron Man; and in 2005 he returned to acting, joining the cast of McLeod's Daughters before taking up his role on Home and Away.
As host of The X Factor, Luke will join judges Kyle Sandilands, Natalie Imbruglia, Guy Sebastian and Ronan Keating, on the search to find Australia?s next big singing sensation.
