On the assumption (perhaps misplaced) that this comment is serious and not a joke, such a sentiment indicates extremely poor risk assessment. Native Australian fauna represents such an extremely small risk to tourists that it is not worth considering. (But obviously if you do encounter any dangerous looking fauna you should treat it with respect.)

But I do agree with the grandparent comment that this extreme level of airport search intrusiveness does legitimately make Australia a much less attractive tourist destination. And btw, as an Australian, I feel somewhat the same way towards the USA and its intrusive airport searches (which is what we are slavishly copying).

You could just visit the other 99.6% of the country that Sydney funnel-webs don't inhabit?

DEI petition to increase the number of female funnel-web spiders in employment in Sydney when?
