Training rooms for hire in Melbourne?

Hi,
Does anyone know of any good inexpensive training rooms for hire in Melbourne? Preference is Queen Street/ Docklands/Southbank.

Required for 25 people, 4 round table set up.

Thanks,
Glen

Got no idea on the price they charge, but believe AHRI hires out their training rooms when not being used. Could be an option to investigate

Thanks Cottoneyes I'll check them out.

Just to update on some sources if found:

Polygon Functions & Meetings Centre, 474 Flinders Street (Australian National Institute of Business & Technology ) (best value for money option I found)

Icehouse, Docklands for something different
Melbourne Zoo for something different

RACV City Club, 501 Bourke Street

Last time I found a adv in Gumtree saying that conference room in Swanston rental for $50 per hours. You might check it.
