All this talk of tiers and what, constitutes what, also needs to take technological advances into account.
Compare the cruiser HMAS Adelaide, that served in WWII to a Tribal (built during the war), or Battle class destroyer (entered service within five years of the end of the war), then to a Daring class (wartime design, completed post war).
Compare any of them to an Adams/Perth class DDG.
Now compare the DDGs, not to the Hobart's, but to the decidedly tier 2 ANZACs in their current configuration.
Mk-13 with 40 SM-1MR and Harpoon, two Mk-42 5", 3D radar, ASW torpedoes, Ikara (deleted later in life), 2x Phalanx.
Versus 32 ESSM, 8 Harpoon, Typhoon, ASW Torpedoes, helicopter with ASW Torps and Hellfire. On top of that the sensor suite and CMS is incomparable.
Add Block 2 ESSM the new volume search phased array, on top of the previous ASMD upgrades and it is arguably far more capable than than the DDGs that were literally the tier 1 ships in service as the first ANZACs were delivered as tier 2 patrol frigates.
Technology moves on, maybe AEGIS and 30 plus strategic length vls cells is the new minimum.
