Seems like the font is from ABC's new oneABC font family, that I touched upon in the ABC News discussion a few days ago. It's designed to replace over 1000 fonts in the ABC's current font library, and become their new corporate font. Evidence of this is the new News logo, ABC App, ME, 2017 Upfronts and some parts of the website. Seems now changes are starting to happen in preparation of the News relaunch. Seems like the ABC themselves are having a Corporate Rebrand too.
