Here are some comments from the creator of the logo:

The connected Crosses communicate togetherness and linked people, communities and households (they also look like buildings), be it the town, families or congregation. They also represent the streets and roads of the community.

The colours represent diversity, vibrancy, differences, urban and rural. They also represent the beach and relaxed lifestyle of the region.  

Like the colours, the bottom swish (wave) is also a nod to the region’s beach, sand, waves and lifestyle of the area.
