Lost "Got Talent" Auditions

Hello. I have been looking for years for various full episodes of auditions of Got Talent competition shows from around the world. Shows like America's Got Talent, Britain's Got Talent and Canada's Got Talent are plentiful, but what I am specifically looking for are the earlier seasons of Australia's Got Talent. Season 6 and onward are fairly easy to find, but what I am looking for are Seasons 1-5. I have not found much from those seasons online except for individual auditions and performance pieces, leading me to think it's lost media. I am wondering if the people at the Lost Media forums can help me out with the search. I honestly should've started this a lot sooner but did not get around to it.
