Large Bird Toys
Cockatoos, macaws and other large parrots destroy things. That is not a behaviour problem, it is what the beak is for, and the answer is giving them something worth destroying.
These toys are built to a different standard, with thicker timber, heavier rope, stronger hardware and larger components. Ninos Java is the backbone of the range with solid Java wood pieces, and Prestige Pet and Beak Joy add foraging and chew options at the same scale. Expect to replace large bird toys regularly, because a toy that survives untouched for months is not doing its job.
