Australia's big whistling tarantulas, deep-burrowing, stridulating when provoked, and defined by the continent's absolute export prohibition: the world's legal stock is a closed loop, permanently.
Old world in full: large, fast, defensive, and venomous with documented significance, Australian bites being among the group's best-recorded. No handling. Serious substrate depth, warmth, distance.
Australian taxonomy in this genus remains genuinely unsettled, so sp. labels dominate even inside the country, and the exported loop inherited that softness. Inside it, a handful of breeders set availability, gaps run long, and prices track the closed border rather than any production choice anyone can make.
