Preheat oven to 180 degrees Celsius.

Combine flour, sugar, coconut, and rolled oats in a mixing bowl.

In a separate saucepan, melt butter and golden syrup over low heat.

In a small bowl, dissolve baking soda in boiling water.

Add the baking soda mixture to the melted butter and golden syrup mixture.

Stir to combine.

Pour the butter mixture into the dry ingredients.

Stir until all ingredients are well combined.

Drop level tablespoonfuls of the mixture onto cold, greased baking trays.

Bake for approximately 15 minutes, or until the cookies are golden brown.

Remove from oven and let cool on the trays for a few minutes before transferring to a wire rack to cool completely.
