This is just another component of their tourism marketing plan. Notice how it coincides with the new MadMax movie? LOTR had a huge effect on NZ travel.
Australia is tired of pansy-ass tourists getting stung, bitten, roo-punched, and croc-chomped and getting bad publicity because someone thought it was as safe as Floriduh.
Australia has a goal that when a tourist is harvested by the local fauna, friends back home will all post all the videos of dangerous stuff they'd previously seen on social media, and ask why.
Politicians will be asked to ban travel to Australia because it is too dangerous, even if their friend was an idiot who got what s/he deserved by traveling there, and thank goodness s/he didn't breed before going there.
