It all depends if you just want to watch the planes or take some photos & if you have transport? If you just want to watch the planes then the Aviation Viewing Park is the place. A viewing area with toilets refreshments & a well stocked aviation shop! But if you want to take great photos as well then you need to go to the famous south side spot very close to the start of the new runway! Here if the weather is good you've got the sun behind you, the only downside is no facilities at all! I believe there is a bus service to the Aviation Viewing Park from the Airport, but if you want to go to the south side spot you'll need a car or its a very long walk!
