Hobart changes (tfr of airspace currently Class C A045-A085 and owned by TWR to overlying en-route sector controller), as well as TW/AY/LT/AS, coming May 19, also Class E base lowering to F125 out West, and up the E coast Class A raising to F250, and insert Class C F180 to F250. No idea why.
Couldn’t post link, but on AsA website under “projects” tab, in airspace Modernisation sub-section.
