Posts of the beach and cabins look good. More on the surrounding attractions could work well to appeal to the customers from Sydney and further abroad.
I’d recommend adding more stories. Aim for 3-6 stories per day. These stories could include little snippets such as short videos and photos. Ideally, you could use content from your customers and ask them to tag @kendallsonthebeach in their posts so that you can share them
I would also recommend adding more images of Kiama’s attractions such as the blow hole, saddleback mountain lookout, walks etc. These images will help to really sell the whole appeal of travelling to Kiama and staying in your cabins.
I can see you’re posting in the newsfeed every few days which is ok but aim to post at least once per day in your feed for greater consistency.
Also, let’s max out your hashtags. Add 25-30 hashtags with each post to really help reach a wider audience.
