Not sure about the jump start points you mention, don't have any experience with late model Holden's but connecting straight up to the battery would be fine.
Alternatively could you leave a window down slightly? Only if in a secure garage though.
If you don't mind reprogramming your clock and radio you could always take the battery out of the car and connect it to the charger while away.
