About the function space

The multi award-winning Treasury has excellent service and good times down pat.

The Courtyard is perfect for cocktail parties both small and large. Large market umbrellas are utilised to help cover from rain, hail and sunshine. We have mobile heaters which are accessible year round.

A selection of hot and cold food platter items is available, and will have mouths watering.

You have your own servery window in the Courtyard to access our main bar, or we can arrange a portable bar for you if you choose a drinks package.

Kick off in the courtyard and then if desired, you can be relocated inside after 11pm to continue celebrating in our stylish venue. Or use our venue as a springboard for a late night in the city.
