>gameplan>slowlyVery good approach.
>rabbits for meatDo you hunt and butcher? Some people have an emotional difficulty butchering rabbits or any farm animal, but they can hunt and butcher easily. Good luck regardless. Rabbit crap is amazing for composting into fertilizer. If you make a raised bed you can keep the rabbit cage over the bed for them to crap into it. Then move the cage and add compost and such to help process it into usable soil.

>Any big red flagsNothing that I see off hand. But, since you are using your water tank, I suggest you use containers of whatever size from bathtub to large bucket and have a drip tray under them that will catch all the run off water. You'll be able to reuse it and not waste so much. A shade cloth plus humidity tent might be needed for some plants. The varieties you should look for are heat-tolerant ones. Ones developed and used in your section of Australia will be best of course.
Your cold weather crops can probably be grown in full shade on the shady side of your house or whatever. Having them in a semi-buried sump hole will help keep them cooler. Either in the side of a hill, or at the base of a building foundation. Like if you missed the tomato season, shade cloth and a cool place may allow you to grow them anyway.
