The best part of any area is subjective to personal needs and wants of the individual. Most people say they live in the best area because they love and take pride in where they live. There are trends in certain areas because of popular opinion, increasing value. This changes all the time. No one can predict the future, regardless of what any experts say.
What is popular now, may not be desired tomorrow. This also may not coincide with your needs and wants. It's like asking which is better PS4 or XBOX1, Apple or Samsung? Like every person, every home is different. Finding the right one for you, shouldn't depend on what others think is good for them.
Reviewing and considering your needs and wants is the best way to look for any properly, and is the greatest start in creating a home you can be proud of. I hope this was helpful.

We lived in the "better part of South Lake" and I certainly wouldn't recommend either the new or the old parts of this bad suburb. South Lake has a bad reputation and it's fully warrented. Beware any estate agents in the area and do your own research. If you wish to live close to Cockburn Central then Success, Hammond Park or Beeliar are much better suburbs.
The area people have been referring to as the better part of South Lake is the area on the south side of Berrigan Drive, closer to Cockburn Central. Some people refer to this area as the "newer South Lake" whereas the area north of Berrigan Drive is the "older South Lake".
Hope this answers your question.
