The CSIRO aren't the group who have to cost, pay for, take on the financial risk of or be operationally involved in running a nuclear power plant. Their opinions are welcome but not in any way final. The Chinese might easily be willing to come in and build something as their industry matures, for example, at costs not currently anticipated.

The more pressing issue is the Australian government is a coven of luddites who have taken a bold and consistent stance against any form of advanced industrial progress taking root in Australia whatever and have identified nuclear power as high technology that therefore must be categorically banned. Leaving the whole question an academic one and leaving the CSIRO the only group taking an interest.

The CSIRO renewables plan factors in only 2-4 hours of battery capacity (way less, with some already built) with the rest of the backup coming from existing pumped hydro and an existing Natural Gas plant. one of the reasons nuclear looked worse in the report is that they would have to actually build a nuclear power plant. it might not make direct sense to build nuclear given what already physically exists, but apples to apples it's not quite as clear.

I think not everything that makes (purely) financially sense does make economically sense. There's much more to it that just money (e.g. where do you get the uran from for the next 30 years?).
