Ernie says corrections are in order....

... As for glancing at your forthcoming OZ adventure, a few corrections:

Venomous snakes: yes we have them in Australia but in my 46 years in Sydney, I did not see any other than in the zoo. As for venomous spiders, dying from a bite is virtually unheard of, except for small children in remote areas. There is anti-venom available in hospitals, and the poison is not fast acting at all. We are talking about successful treatment always possible within a few hours of the bite. In Sydney, only the funnel-web and the red-back spiders are an issue. They are not easily found, unless you garden barefoot or without gloves or reach into cavities in certain known hiding places without looking.

Where I lived a few decades ago, we had a few funnel-web spiders in the bush, I used to look for their distinctive round entry holes in the ground, teased out the "beasts" and collected in a jar and took them to a place where they milked them for their poison for research. No worries!

Please do not worry about any venomous creatures in Sydney or in the oceans here. Sharks or Queensland box jellyfish or seasnakes there is another matter. But knowing a few simple rules avoids any trouble.
