As with everything, accepting other people's experience AS their experience, without belittling it because it's not the same as yours, is the key.
As I've said before, I'm in semi rural NSW, not QLD, and our saltwater lake, Lake Macquarie, has sharks in it. The boys used to swim in it but they're less inclined to now because last time they were there they saw a shark. Hammerhead sharks have been washed up on a nearby beach.
We've seen a red-bellied black snake on our kindling-collecting bush walk out back of our place, and a brown snake in our yard. These are common as anything in our area.
Redbacks, white tails and Huntsman spiders are our most common tricky spiders (plus the daddy long legs spider, and the black house spider) although occasionally we have wolf spiders in the house too. Not seen a funnel web yet, although the husband has.
We have the fuck-off huge cockroaches, and the tiny ones too (oh yay) which are bastards to get rid of.
Although this isn't a thread about the good things, we also get in our backyard:
ringtail and brush tail possums
bandicoots
rats (ugh)
antechinus mice
and so many birds! lorikeets, galahs, corellas, sulphur crested cockatoos, king parrots, eastern rosellas and we once even had a gang gang. We have kookaburras, satin bower birds, spinebills, mynah birds(native) and many more - and then, to my delight, we once had a tawny frogmouth!
It's all area dependent. But if you don't like wildlife much, especially wildlife that likes to come into your house (had a possum in the house at least 3 times, and I mean in the HOUSE, not the loft) then it's not ideal for you.
