Dont know if this will work or not.....I just found this video clip of Heath when he was in an Australian Soapie called Home and Away.......if you move the timeline to 1998...you will see a caption "Scott takes advantage of naive Sally"...click on the box and watch the video of one of Heath's earliest tv roles......
http://au.tv.yahoo.com/home-and-away/timeline/If you look throught the timeline, you will also see videos of other Australian actors in early roles, before they made it big overseas.....Guy Pearce, Melissa George, Julian McMahon, Danni Minogue, Isla Fisher, Ryan Kwanten, Chris Hemsworth, and a young Leyton Hewitt in a scene with his wife to be Bec (Cartwright) Hewitt.....
