We went on holiday for a week, but stayed at another Air BNB in Byron for the first couple of days. Coming to the Beach House was so refreshing! It had everything we could have needed - right down to the tiniest of details. & unlike Byron, you don't have to pay for parking everywhere you go.
Our favourite things were the heated pool, the beach within walking distance (especially for sunrise), the restaurant recommendations & Netflix on the TV. We enjoyed our stay, even though the weather was rainy some days.. we were still able to enjoy swims in the heated pool.
Casuarina is a beautiful community - tight knit. People are so kind!
I'd recommend:
Sunrise swims,
Nectar Juice House (for delicious sandwiches & juices)
Kingscliff for a walk & also visit the cafe (Stone Studio - for almond croissant + the BEST coffee)
+ Dreamtime Beach / Fingal Heads lighthouse.
