A versatile space, it is easily dividable into four separate sections. The Heritage Ballroom is located in the restored GPO wing, and in years gone by was the first telegraph exchange in Australia.

Fudge by Rich As always, absolutely delicious with amazing feedback from all who tried the product! Beautifully packaged up for us, delivery process fast and reliable, and Nicole couldn't have been more helpful in turning around such a large order on such short notice ensuring we had everything needed for the trade show... Think I have a new favourite flavour too, the Rocky Road is to die for!!

Novotel Sydney Brighton Beach

What a professional events team...

Novotel Sydney Brighton Beach "The events team at Novotel Sydney Brighton Beach are truly professionals at what they do. The organisation in particular of the banquets team - always so helpful and ensure that our seminars run smoothly. The only minor suggestion that I would make is more labels to indicate the types salads and sandwiches that are on offer on lunch buffets."

The communication from the event co-ordinator in particular was excellent prior to our meeting. It was organised at short notice and she showed such high attention to detail which I really appreciated."

Rendezvous Grand Hotel Melbourne

Really good quality & great value... best external meeting venue in a while!

Rendezvous Grand Hotel Melbourne "The room was appropriately presented, with everything we had requested already in place. Morning tea and lunch were more than ample, and was 'yummy'! Really good quality and great value for money. One of the managers even said it’s been the best external meeting venue he’s been to in a while."


The venue, as well as the staff, location & atmosphere was second to none!

Dockside "We held our Staff Christmas party at Dockside this year - the venue, as well as the staff, location & atmosphere was second to none. From the moment I booked the venue, the service was fantastic. The event organiser kept in contact throughout the year, reminding when things needed to be done. Everything went smoothly on the night of the party, the food was amazing, the staff were excellent & the event manager on the night bent over backwards to help with...
