Yeah... just came back from Australia end of Sept. Hand-carried my DSLR body with attached lens & flash unit. No prob with that. Originally wanted to bring tripod but didn't. Are you bringing your tripod? If yes, very likely have to check-in the tripod.
i brought along a crumpler bag to put the camera stuff. the tripod i literally handd carried. no case at all. my backpack was emptier than when i went there, so i put the tripod into my backpack to check in on my way back (on my own accord).
