Similarly we opted to spend last Saturday night doing an overnighter test-out trip with the new shiney Lifestyle CT, out at the Booloumba Ck site neat Kenilworth. We arrived at about 5pm to find the place emptying out and passers-by warning us that the creeks were rising and that we wouldn't get out if we stayed the night.
We turned around and moved on to the Charlie Moreland site up the road, and crossed over the (then) sedate and hardly running creek causeway on the way in and setup for the night in heavy rain. Checked the causeway in the morning and it had risen 1m crossing the road by 500mm, running very fast, and no-one was going home that way! There were 4 groups camped there, and some had 2WD's who were going to be there for days I'd say!!
We packed up and headed out westwards on the Dry-Weather Only logging road towards Jimna, and made it home that way. Much fun, and an extra 90 mins wet and slippery drive, but there was no way I was risking the crossing.
Would love to see the pics and video of your exit jetcrew! Here's ours.
