For anyone who’s interested, I happened to find these (whilst researching something for another thread).
Seven Network voice-overs:
Sarah Aubrey (promos; female - 2005>)
Matt Wills (promos; male - 2004>)
John Deeks (network broadcast sponsors - 1980s>)
Nick McKay (news - 2012>)
Rod Mullinar (sport - 2012>)
Graig Willis (AFL broadcast sponsors - 2012>)
Edit
Shae Brewster (7flix)
Duncan Fellows (7mate)
Not sure about the other Seven male V/O though.
