By now, it should be rather obvious that Peter Overton partially models his newsreading style on Brian Henderson’s and that the current main presenter of Nine News Sydney has a great deal of respect for the icon.
I’d have to find the report which backs this up (which would’ve been published around the time last year when Pete marked his 25 years since joining Nine) but if I’m not mistaken, Brian Henderson was/is actually Peter Overton’s mentor. Hendo has even allowed Overton to use his iconic signoff, an offer which Pete has respectfully declined of course.
UPDATE: Found the article! Paywall alert since it’s a “Premium Article” from The DT, but it pretty much backs up what I’ve been saying.
