I probably wasn't clear. The ROI would be a comparison between current HQ and a different facility setup. I don't think either of the 2 scenarios would be profitable and probably both require government subsidies, but I would expect the cost to be similar and might open up properties to be filled with International travellers from bubbles in order to kick start tourism. Ultimately they should be looking at it from that perspective if they actually believe we will need facilities for at least another 2 years which is what the govt have indicated.
sounds way too forward thinking for this federal government unfortunately.
