Is it true that people speak Australian language In Australia, and it's very difficult,?

so one day American tourist was absolutely confused, because when he arrived to Sydney, he could not find his hotel, as he was shown a mirrored sign in the department store across the road which read kraP ttayH yendyS, and he could not read Australian, and whenver he asked what kraP ttayH yendyS was, he received shrugs and "no speake Englese", and he had to spend three nights in Sydney park, on a bench, and heard most appalling sounds, coming from the bushes, and he thought that it might have been a stray Bunyip, when a friendly policeman explained to him, that, in translation from mirrored to English kraP ttayH yendyS means Park Hyatt Sydney (and not what he though, especially "krap") , so he (the tourist, not the policeman) moved in, took the first shower in many nights and forswore to go out without a phrase book and a hired guide?
