There you have it.
Apparently, a BBC series appealing to teens, thuogh it appears to be one of those filmed-in-Australia things that is largely cheesy, but chock full o' scantily clad nubile young females and buff, manly men. See, for example, Cleopatra 2525 (note archaeological connection) or The Lost World (note faint archaeological connection). Maybe they're filmed in New Zealand, I dunno.
