Undara Lava tubes of north Queensland. Arches, cave-ins and deep caves to be explored

We need an international rule that a date be included in every web site.
 The question is whether a site is still current. Clues and intuitions are used but....
 For instance, seeking a shuttle bus timetable for a strange location, well, who can tell whether or not it is still a goer. Has such and such an airline gone out of business?  Is that review from 2002 or 2014?
Give us a break!
