The Cross is for Tourists and 18 year olds ( who havent realised its a crap night spot yet )
Any self respecting Gay person wouldnt be seen dead in the cross.
For Grimm I would say Newtown ( the New Gay area - biggest gay population now ) and Oxford St ( The old Gay area - has the biggest gay bars ) would be more fun.
Sydney as a whole is less 'Gay Friendly' ( ie needs to make a point of stating it all the time ) and is just Gay accepting ( ie there isnt really Gay only places in newtown - its just a mixed bag and not an issue - Oxford St still has a few places but thats more for the sake of attracting Gay tourists and being sleazy pick up joints )
Back on topic.....
Funnell Webs are all over sydney - but hard to find.
Snakes are mostly in the bushy fringes not in the city.
Most native stuff you would see outside of a zoo in Sydney metro is Possums, Owls, Harmless spiders, Bats and a myriad of birds like Cockatoos, Galahs, Lorikeets and Kookaburras. ( and lots of introduced ones - pigeons, minor birds etc ). If you are around the Harbour there are about a million seagulls too )
I have only ever seen two snakes within urbanised areas. Not much for 28 years of being in Syd.
Last shark fatality was in 1962. But there have already been a few shark alarms at Coogee and Bondi this year - no attacks this year.
