I live near terrigal. And if your going there i have a few suggestions
1. DONT go to woodport inn. Its a major sh#&hole!
2. There are often alot of police in Terrigal iself so be careful
3. If you do have quite a large party at your place then it will DEFINATLY be gatecrashed
4. There are some pretty bade "gangs" in terrigal, and avoca for that matter, and you DONT want to get into a fight with them, trust me
5. There is NO surf at terrigal. its seriously like a lake! Avoca isnt to bad but there are heaps of beaches around to choose from!
And that's bout it. Otherwise its a great place!
