Karstens Melbourne is a purpose-built conference and training venue at 123 Queen Street in the Melbourne CBD, with 16 conference rooms across more than 2,000 square meters and a largest room for 180 people in theatre layout. It spreads over levels 3, 9 and 12 and is part of a national network of Karstens venues.
Seminars and company events
The venue serves board meetings, leadership workshops, training seminars, conferences and hybrid events. Rooms can be set in boardroom, classroom, theatre, U-shape and cabaret layouts, and room sizes can be adjusted to final delegate numbers. Function rooms are also available for presentations, networking events and company gatherings, and mediation rooms offer a quiet, private setting.
Room hire includes a ceiling-mounted data projector or large LCD screen with HDMI, presentation sound, and a whiteboard with markers. Wi-Fi is available in the breakout areas. Onsite support staff help with setup and changes.
Hybrid events are offered in two forms. Standard hybrid uses microphones and an HD camera so remote participants see the presenter and the slides. Hybrid interactive adds a screen so remote participants can be seen by the room and join Q&A. Equipment is matched to room size, from small groups of 2 to 8 up to larger rooms of 37 to 100 in-room participants.
Weddings and receptions
Karstens does not market weddings. It sells corporate meetings, training and functions, so couples should look elsewhere. Company receptions and networking events fit the function rooms, though the official page does not state reception formats or numbers.
Rooms and capacities
The Melbourne venue lists 16 conference rooms on levels 3, 9 and 12. Individual room names and capacities are not given on the page read, only the largest room at 180 people in theatre style. Delegates use breakout areas for catering and networking, and the venue describes its rooms as light-filled and pillar-free. Organisers who need exact figures per room should ask the team for a quote and floor plan.
