"Healthy Irish beef stew with an Aussie-style twist, scaled to feed 10 people. Use metric units. Make it hearty but lighter, with beef, potatoes, carrots, onions, celery, garlic, herbs, and a balanced broth. Include an Australian-style touch such as a small amount of red wine, bush tomato seasoning, or a subtle vegemite-style umami note if appropriate, while keeping it clearly an Irish beef stew. Provide a complete recipe with ingredients, steps, cook time, and serving suggestions."
