I just wanted to say a very HUGE thank you for allowing us to use the extra function rooms. That made the party very special for us all. Helen was extremely helpful and friendly. Jude gave exceptional customer service and had a pleasant nature. The food was great as well. The girls loved the experience at the Osbourne. I will definitely be singing your praises to anyone who is looking for a venue for a function.

I just wanted to take the opportunity to say a huge thank you to all the staff involved in our son’s 21st Birthday on the weekend. We had an absolute ball, the set up was awesome, food yum and all the staff involved were fabulous. If you could pass on our thanks to them that would be great – thanks so much for everything.

I’d say we “nailed it” this afternoon and I just wanted to say a BIG thank you to you and your team for making our End of Year function such a successful one!! I had such positive feedback from all our staff – everything (especially the food) got a big tick. Lexie, you are such a pleasure to liaise and work with, you are always so calm and nothing seems too much trouble.Wishing you a very Merry Christmas and an exciting New Year with a new addition to your family.

Just wanted to let you know the signage looked amazing. The function space was fabulous. Your staff, as always, the best.


Your staff on the night went over and beyond what was required and expected of them. our bar staff were outstanding, they were both an absolute credit to the function venue and need to be thanked for their outstanding bar skills and wonderful personalities. Honestly, we could not have asked for anything further from one person at your hotel. Sophie's night was outstanding in large part to the venue and your staff. Our guests have provided us with such fabulous feedback of their experience at your hotel, not one negative thing was mentioned. Some are actually now wanting to hold their next events at your venue.
