I like the first one, but the Engineer in me, immediately started asking why aren't they using the roof for solar panels if it's out in the outback???
One of the major issues that everyone forgets with sticking projects in the outback is that it's a very long way from anywhere - to drive from Darwin to Adelaide is about the same as driving from Lisbon to Warsaw. Stick something in the middle of that and you've got a long drive to get there from either end. (That's even assuming you've chosen something on the Stuart Highway, and not somewhere even more remote). Building costs are going to be massive as you need to bring everything to the build site, along with all of the builders, who will need accommodation whilst you're building (so add more cost for their accommodation, food, travel away on weekends, etc.). Once you're up and running, you need to pay for people to staff the site, and they're definitely going to be charging a premium for being stuck out in the middle of a desert. You're also going to need to sort accommodation for them, as even if you choose a relatively large town to be nearby, like Alice Springs, it's unlikely there will be enough empty housing to accommodate all your datacentre staff, so yep you are going to have sort something out there. Even if a lot can be done online these days, you still need a physical presence onsite - security, people to look after hardware, etc. After all, having staff drive a dozen hours (or more!) to get to your facitlity to fix something is not going to keep your customers happy. Also getting spares, etc. will be a slow and expensive delivery problem, so you're going to have to keep a lot of spare hardware on site...
Outback facilities, sound great on paper, cheap land, not likely to be damaged through flood or fire or any of the other myriad natural (or man-made) disasters that could affect other Datacenters, but the costs involved with building and running one would be massive....
