LOL Her enthusiastic fervor was what made me laugh, so liked her. The one you posted i think back then was seen as a Huntsman, not sure. Was surprised to hear from that oe last, there are some 250 different Huntsman. Think she said. I always thought the thickest and furriest was the tarantula. Seems the Huntsman is considered the biggest (is it the legs), but the picture i have in my mind as the sturdiest, the thickest and furriest is a tarantula. Gotta solve the mystery, so search - the thickest, sturdiest, hairiest, fuzziest spider in australia - https://www.google.com/search?client=firefox-b-d&q=the+thickest%2C+sturdiest%2C++hairiest%2C+fuzziest+spider+in+australia+is+...
Ok, the photo here looks like what you are talking about, and what i remembered as a tarantula, now will read to see what it is.

Sensing the world with hairs and pits
All spiders are hairy - like us. Spider hairs are part of the hard outer cuticle (the spider's 'skin'). Unlike us, spiders use their hairs (which are often greatly modified) to perform an amazing variety of tasks - for sensing their world, in courtship displays, for moving around, and in defence and prey capture.
Sight is our most important sense. However, most spiders have very poor eyesight and many are active during the dark night hours. With a few notable exceptions, their sense of the world is obtained through specialised sensory hairs and pit-like sense organs in the cuticle. These hair and pit sensillae are especially associated with the spider's limbs and mouthparts. Connected at their bases to sensory nerves, they provide spiders with the sensory experience and feedback needed to survive and function in their world.
Hinged, touch-sensitive hairs on the legs help the spider to move freely about its terrain and are important in interactions ranging from mating to prey capture. Chemically sensitive, hollow-tipped hairs found at the ends of the limbs and on the mouthparts are the spider's tasting organs - those on the pedipalps are used to sense the chemicals associated with mate recognition.
Another stimulus to which spiders are incredibly sensitive is vibration. Vibrations transmitted through air, substrate surfaces and even water can be sensed by spiders.
Air vibrations and currents are detected by slender, vertical hairs called trichobothria, usually found on the upper surface of the three outermost limb segments. These hairs are easily deflected and their 'ball and socket' basal hinge allows them to respond to air movements coming from any direction. This high sensitivity to air-borne vibrations can alert the spider to the wing beats of an approaching moth or fly, or the presence of a wasp predator.
Substrate vibrations, induced in web, leaf , ground or water surfaces by nearby disturbances (such as prey, mate or predator movement), cause slight movements in a waiting spider's limbs. These movements can be directionally sensed by tiny 'strain gauges' in the cuticle called slit organs (or lyriform organs when several are grouped together, as at the tarsal-metatarsal joint) that react to any slight deformation of the cuticle. The sensitivity is such that spiders can readily distinguish prey movement vibrations from those of a courting male or the background noise of wind.
Slit organs are also somehow involved in the spider's ability to 'memorise' directions, for example, the return route to its burrow after a hunting trip. A number of tiny 'slit organs' placed around the bases of the silk spinning spigots on the spinnerets appear to be involved in the sensory monitoring of the movements of the spigots and the emission of silk during spinning, the control of which is still poorly understood.
Near the end of each limb is a tiny pit, dome or peg-like structure called the tarsal organ. They appear to function primarily as moisture and temperature detectors.
Internally placed joint receptors and external sensory hairs (usually short hairs adjacent to joint membranes or longer hairs that span joints) keep the spider informed of its limb positions (proprioception) during movement. This ensures that the spider moves in a coordinated way.

That's your spider, i hope.
