Caution Traffic in the Melbourne Area
"To facilitate more separation between coastal VFR traffic and instrument approaches to runway 34 at Melbourne, the lower level for class C will be dropped to 2000 feet along the northern coastal route from November 8. This also means the recommended cruising levels along the entire coastal route will change. Check the new details carefully on the VTC Inset, which is part of the Hybrid VFR map; just zoom in.
Following the old recommendations means you will fly head-on at the same level as those flying by the new ones!"
ie no nonsense, cut straight to it (OzRunways bolding, BTW).
