I would bring the binata and capensis inside.
Depends on the form of binata. There are some that naturally go dormant, and can survive very cold temperatures.
The dichotoma is well known for surviving cold temperatures in dormancy, as it is a form from very southern Australia. Multifida is a more tropical variety, but can go dormant on occasion if temperatures go low enough, so I would assume the hybrid, Marston Dragon, would also naturally be able to take dormancy.
