The night of 4th September coincides with QBE Riverfire. So for those travelling from the Northside of Brisbane, or anyone else who is travelling through West End, South Brisbane, Kangaroo Point, etc, please be aware of the road closures, and make alternate route plans if you need to, to get to the venue at Stones Corner.
Here's a link to the Brisbane Festival website, stating Riverfire road closures on the night. Also keep in mind that it's going to be a big night as far as celebrations in and around Brisbane, so it may take a while to get a taxi back from Cloudland to the venue (a coach is booked to get you from the venue to Cloudland). You may want to consider booking a taxi ahead to ensure you're not waiting too long!
