You will need a car when down here. Other than a few surf breaks, everything is accessible from a gravel road. There is a very limited bus service between Dunsborough and Busselton. Dunsborough is 13 km drive from our place, and Margaret River is 40 km. It takes us about 9 minutes to get to Yallingup beach. It takes less for the sea breeze to reach us as Smiths Beach is only 5km away as the crow flies. Restaurants /wineries start from 4 minutes away.
