I live in Byron Hills which adjoins Baywood Chase. I have lived there since 2002 prior to children and now have two boys age 3 and 8. It is a great place for young children due to the above comments (OZLocal) and most importantly I love the community.
Probably Baywood Chase. There is a beautiful lake in Baywood witha bike/walking path around it, great for walking the dog, bike riding, etc. There is also a picnic are and parks around the area. It's very clean and absolutely FULL of families with young kids (0-10) I know many people that grew up there and it truly is the most family friendly area in Byron. Next to Baywood Chase is Suffolk Park. The kids are much older there so basically teens, and I'm pretty sure there is a skate park there as well. Overall, I recommend Baywood for its affordability and lifestyle.
Baywood is good for all of the above. I live in Suffolk Park beachside with young kids and its a few minutes walk to the beach. Lifestyle is great there , go to the beach with the kids after work, bus to school not far away, seems like there are a lot of primary school children at the bus stop at the moment . I cannot see my wife ever wanting to move.
