In Victoria, Australia we don't really have vibrant Coral Reefs, although I was wondering if the rock under the tide line would be as good as say rock in Queensland where there're Coral Reefs. My best guess would be no they're not definitively the same, like Victorian Live Rock would probably host life that typically live in your 14 C° to 19 C° range on average, however Queensland Live Rock is actually from an environment where Corals naturally grow. Queensland ocean temps average at 20.8 C° to 26.7 C° So basically Victoria's hottest average water-temp, is Queenslands coldest. I was thinking maybe if you collected live rock at the peak of summer in Victoria it might maybe be a little better.
