Cook noodles following packet directions. Drain and set aside to keep warm.
Meanwhile, heat a wok over medium-low heat. Add Five Tastes Laksa Paste and cook for 1 minute or until fragrant.
Add creamed corn, coconut milk, spring onions, lemongrass and water, increase heat and bring to the boil. Stir in fish sauce and crab meat, cover and simmer for 5 minutes.
Place noodles into serving bowls, reserving a few for garnish. Discard lemongrass and spoon soup over noodles, top with reserved noodles and spring onion.
