Top Mid-Sized Event Spaces in Australia (250–800 Guests)
The most popular type of conference space that we supply is medium-sized venues. 250-800 Guests is still a considerable number, but it is still very manageable, especially compared to 1,000+ Guest conferences. If you’re planning a corporate AGM, your company division’s yearly get-together, product showcase, association forum, or regional summit, this guide is for you.
We’ve selected standout venues across Australia with a capacity for 250 to 800 attendees—each with event-friendly layouts. This list is selected based on our experience as guests and suppliers and feedback from our corporate customers.
