If staying in Perth WA then stay in Blue Water Resort in Duncraig. We stayed for 3 weeks with 9 of us and had a great time. The house is fantastic with plenty of room and the outdoor area is great. My kids were never out the pool. Maram the host is lovely and always on hand should you need anything. You will need a car to get places but this usually the case wherever you are in Perth. It is only a 20 minute walk to the train station though. House was clean with great cooking indoor/outdoor and sleeping facilities. If you stay here especially if you have kids you won’t be disappointed. Highly recommend.
