Final answer:
Nestle utilized a Market Development Strategy by taking its successful Maggi noodles from South Asia and introducing them to the Australian market.
Step-by-step explanation:
When Nestle introduced its Maggi noodles in Australia after finding success in South Asia, they were implementing a Market Development Strategy. This strategy involves taking an existing product and introducing it to a new geographical market. This differs from a market penetration strategy, which would focus on gaining more market share in the current market where the product is already being sold. It also differs from a product development strategy that implies developing new products for the current market, and from a diversification strategy where a company introduces new products into new markets.
