As others have said, you should be fine at your stage of pregnancy, as long as you are healthy. Double check with your airline though when you go to book, but it's generally about the 36 week mark when you need a dr's note to say all is ok to fly for the airline to let you on.
I have heard of some airlines staff refusing someone (a year or two ago) because of their size, they were thought to be further along in their pregnancy then they were, and as they didn't have a dr's note, they weren't allowed on. So, it may be better for you to have a dr's certificate regardless of the fact that you are still okay to fly, just in case the airline gets funny.

Tbh, your probably safer flying. If something happens to you halfway across the nullabor your nearest echelon could be hours away. When flying there is generally someone who knows first aid on the plane, and your only a short time away from the nearest airport.
I did the Nullarbor trip when I was pregnant and back again. I was 30 weeks & 33 weeks on the way back. We checked with the dr before we went - and he said it was okay to drive that far, just ensure plenty of stops for walks around etc, although he'd have preferred it if we flew. But, we needed to drive that time. But, both ways are doable, depending on your health. smile
