Welcome to the Q&A Forum

You can find some good brandable domains at https://www.brandaisy.com

AUguides.com would probably be the best one of of the available you've listed.  i'd avoid anything with two letters together a la venueexplorer.com  that being said the trends right now are for short unique bit.ly bizzy.com etc.  you might go back to the drawing board but I dont see anything wrong with AUguides.com  if you brand it correctly you could have something special .

Actually, we did recover from the original Panda hit last December so "YEEEEHAAA!". We combined a bunch of similar categories and started writing descriptions for categories that were missing them. Unfortunately, we got smacked again by Panda 3.7 in June and haven't recovered yet.
