WELLY"MONSTERS" do they exist..??

I thought I might share a couple of my own experiences with some other like minded people, or even skeptics.
The experiences come from living for nearly 10 years, half an hour west of Burleigh Heads up in the Hinterland, verging onto the Sringbrook Mtn range. The Springbrook area is a hot spot around Australia for the Australian Bigfoot (Yowie) or Aboriginal (Dooligahl), even a lot of paranormal activity !

We first rented our house, that we eventually brought, it had just been built so we were the first people to rent it. A pretty cool style type tree house 18ft off the ground on a steep embarkment overlooking the state forest, with tall gums running right up to our house. A few months had gone by, when about 11pm one night all the next door neighbours dogs and my dog (BillyBoy) started nutting off big time.
We didn't really think much of it, as it was happening quite regularly at night around the same time, then all of a sudden the house shook with an almighty thud and I mean shook. I jumped out of bed and went out on the deck only to hear heavy bipedal footsteps 50 m away crashing down in the bush, I knew it was way too big to be a human or even a wallaby. I kind of guessed what it was, quietly shitting my pants. The next day I confirmed my belief by trying to shake the steel poles of the house myself, but nothing, not even a little wobble.
A few weeks before this happened, which I find weird is that my mother in law had given me a book to read about "Mysterious Australia" by Rex Gilroy. The book was based on lost cave systems, UFOs, Thylacine's, Ghosts and Yowies, the Yowie is what got me interested.
Having grown up in NZ hunting, nothing could really come to threat, except a pair of nasty tusks from a wild boar, but coming to the Australian bush and dealing with spiders, ticks, leaches, snakes, panthers! And let alone Yowies. It's a whole different kettle of fish for myself.
About 9-10 months ago weird stuff was happening around the house between 11pm and 3am for a few nights, branches were being broken, loud noises not far from our house, but every time I would go out and check they would stop, shine the torch light, nothing. I had told my next door neighbour about the Yowie, he always used to laugh at me. Around this same period he was out on his deck at 3am off to work, when he heard this most gut wrenching sound not far in the bush, that made his hairs stand up on the back of his neck. He's a burly hardcore bikie bloke whose been around the traps so to say? he said that he had never ever heard that sound in the Aussie bush ever before.
The same week my wife kept on telling me the bio-cycle is leaking, cause she could smell this rank smell, but only at night. The next day I looked and smelt every where, nothing. That night we were both upstairs about 10pm, then we both got this pungent Sulphur smell similar to rotten eggs or volcanic hot pools, like Rotorua in NZ. This was the first time I'd ever smelt this in Australia and pretty much is the smell of the Yowie from other peoples sightings or close encounters.....?
I truly believe they are there in the bush, not just in Australia but other parts of the world as well.
Anyone else had different, similar experiences in the Aussie bush or beyond.....? Crypto or even Paranormal..?
