Welcome to Perth first and foremost 😇 Depends on the month we are talking. It’s getting warmer now and it will peak up from October and last until January. It’s not as humid as Mumbai but rather a bit dry like Delhi. Winters are normally accompanied by rain so it does get a little cold.
Please dont be worried. The question depends on which month you are coming in. If you are coming in the next few months then all indian clothes will work just fine as it will turn from Warm to super hot. If you are planning to come after February, you will need warm clothes for your toddler. Its wise to come here and buy warm clothes from Perth because we all know 1 year old will very quickly grow off and wont fit in if you buy now..
