Well , we have white backs [ mainly indoors - they love houses ] , lots and lots of Red Backs , spent all this summer killing them , the house was surrounded .
Wolf Spiders - almost as big a body as Huntsmen .
White backs and Redbacks are mainly a summer problem , Wolf spiders seem to be year round , but prefer the outdoors . [ Spiders here in Melbourne ]
As for Snakes , Red bellied Black snakes and Tiger snakes found in the Suburbs , creeks , flood plains , Parks . Heck a neighbor found one under his rose bush once [ Tiger ] and killed it with a spade ..
When I was 12 I killed one with a knife one summer evening just behind our house , the neighbors cat was killed by a tiger , and when they concreted the local creek , 3 of the workers were bitten by tigers in the first week of work .
Brown snakes in the coastal areas heading north , death adders and copper heads and the rest in the bush .
So I guess , Tigers , Browns , Death Adders , Copper heads , and Red bellied blacks , but mostly Red Bellied Blacks , Ive seen plenty over the years , as well quite a few Tigers . Snakes dont hibernate in Oz , MUCH ! only the ones in Alpine areas , but there known to come out to sun themselves even when there is snow on the ground ... So just because your playing in the snow is no guarantee ...
So out of this lot , the Eastern Brown would be the most aggressive , but then around April is Tiger Breading season , and the tigers have been known to be a little edgy at this time of year .
And Death Adders are no cutesy pies either , as well the copper head has been known to be testy , so I guess all of the top 5 can be mean when they want to .
Best to just avoid them , and thats why i like lights with flood , I want to see everything in front of me
