Return the browned wallaby shanks to the pot. Pour in the stock or water, making sure the shanks are mostly submerged in the liquid. Bring the mixture to a boil, then reduce the heat to low, cover, and let it simmer for 2-3 hours or until the wallaby shanks are tender and easily pull apart.
6 Serve: Once the shanks are tender, remove them from the pot and place them on a serving platter. Spoon some of the braising liquid over the top. Serve with steamed rice and sauteed greens.
