The consulate will always help you whenever it can, and usually you won't hear any comments (though they may think it). So that isn't the risk; however the warning may have been issued due to contingency plans being put into place to evacuate non-essential staff at the next crisis, in which case the consulate will be severely understaffed and wouldn't be able to help. The Australian gov't is more cautious now in its travel advisories than some other countries due to the Bali bombing (which it didn't warm about, despite having very specific information about the plot, which wasn't revealed or acted upon). They don't want to be blamed for withholding info again (as much politics as useful policy).
