To answer barons question,I believe yes they are the only poisonous mammal.
Now to answer Sugar Creeks questions.
I live about half way down the eatern side of Australia back from the coast up in what is called the Great Dividing Range. This is the spine that runs from the bottom end of Cape York Peninsula (the pointy bit at the top) right down into the middle of Victoria state. This area contains Australia's highest mountain which is a meagre 7,250 feet. I live in the northern part of New South Wales state,our altitiude ranges from 3 to 5,000 feet. Someparts of this region have 3 or 4 snowfalls a year,we usually only have sleet and cold here. It last snowed here to a depth of about 1 to 2 feet in July 1984. We have beautiful summers that get up to 36c at times but generally are around 25 to 28c.
A cold winters day will get down to a maximum of 5 or 6 c but generally they are around the 12 to 14c.
We get most of our decent rainfall from late November to into April, (late spring to late autumn) Though sometimes we can get good rain during winter which is great because it keeps the frosts away. We had 45 frosts this last winter. One bitter morning down to minus 9c.
Our average rainfall is 34 inches but that can get up to 45 inches sometimes (not recent ones though we have been as low as 16 inches in the past 4 years) We are heading for probably a 25 inch year this one. Sorry for jumping between celcius and fahrenheit, a lot of country people still use inches and celcius instead of fahrenheit.
We don't grow crops here on our place,just grass. Some locals do plant fattening crops of oats,rye grass in winter and forage sorghum in summer. This area is fairly heavily fertilised with superphosphate,we use an organic type fertilizer with excellent results,far out doing the super.
our area is fairly old as far as Australia goes established in the 1850's. Our little town is called Tenterfield which is noted for the birthplace of federation this happened in 1901,prior to this date all the states of the time governed themselves,this was the start of Australia as we know it today. (look up tenterfield.com.au and see what you get. The Tenterfield Star is our local newspaper its available on the web too.
Our government loves to look good in the eyes of the world,lots of produce is imported we have such a diverse climate that Australia would grow every crop that could be grown on earth. Presently there is a glut of oranges in the citrus growing areas thousands of tonnes of them are just being dumped. Its an absolute disgrace. Our government at present offers us the best for our country's future as the alternative is just nothing. If they were to get back into power we would once more go back into the welfare type state that we had when they governed 10 plus years ago. The labor party just loves dole bludgers and those that aren't very keen on work.
Hope I haven't waffled on too much. New Zealand fascinates me too its considerably different to us in climate,terrain,language etc.
Anymore questions just ask.
