Seven Perth is a quality example of how people view news. People don’t watch news just because of sets (only us people here on MS), but more on the substance and quality of the bulletin.
TBH, Seven Perth does have some rubbish content these days, but people still trust them because for years they were ahead of Nine in terms of presenters, content and appearances. Nine is trying to claw back with good content and a great set, but unfortunately it seems that Perth viewers doesn’t really give a crap about the sets.
Nine News Perth is probably very similar to Seven News Sydney and Melbourne which were known for presenter changes every 3-4 years, while Seven Perth is basically the Nine News Sydney and Nine News Melbourne on the West Coast, and for as long as Rick and Sue stay on Seven, I don’t think many Perth viewers would switch to James McHale, Narelda Jacobs or Tim and Emmy any time soon.
