What’s the weather like the first week in December? I assume it’s all shorts and T-shirt’s? Or are jeans recommended for bushwalks?
It's hot in December so shorts and T-shirts are fine, even for bush walks. You may want to bring loose, lightly fitted (cool) long-sleeve tops and trousers for the evenings, not because it's cold but to help prevent mosquito bites. There is bug repellent provided if you feel it's too hot to wear long sleeves.
