Taking the second point first, the Anthropic facility will likely to contract for its own renewable supply, use its own batteries, and supplement this with locally extracted gas.
Essentially, a data center is a large shed, built on a concrete pad. There will need to be a lot of plumbing for cooling, & power installed. After than racks of equipment are trucked in, bolted down & plugged in. After being built, a few people are needed to guard the premises, clean & carry out maintenance. The programmers & other software staff are elsewhere. So there will be very few long term jobs in Queensland, or Australia, from the facility.
Some data centers dispense with the big shed & simply put the computers in shipping containers, looking much like a big battery.
One area which might take off in Australia is plug-in solar panels. In Europe these are seen as being for balconies of apartments. However, in Australia they may become popular for detached houses. The practical limit for a plugin system is about 7 square meters of panels. This is about as much as you can hang off a balcony & as much as the household wiring can easily carry. However, adding a battery to the system could provide all the off peak energy a small home needs. One potential application would be a standalone solar carport to charge an electric car.
