I also lost power for about that long in 2022. I evacuated Sunday afternoon after the power first went out. Returned Monday afternoon (needing to explain myself to UQ security staff so they would let me through the only not-flooded route to my place, which required driving through uni grounds and up through pedestrian areas) and brought my stuff out of the freezer back to where I was staying temporarily. The ice cream was mostly but not completely melted, so the rest of it recovered alright.
