We either do something at home and let the girls stay up late (9 or so - they usually sleep in) or head to a family event. We are going to the Zoo again this year which is Happy Zoo Year in Perth and it's awesome. BYO picnic dinner and drinks plus 4 hours of awesome entertainment and music. They do the countdown at 9pm and a small fireworks display. It's brilliant. We'll had home afterwards and put the cherubs to bed then probably continue with drinks in our pool - bliss!
