Yes, it's standard to serve alcohol at conference venues in Melbourne, especially during networking sessions, evening events, or receptions. Many conferences include social events where attendees can unwind and chat informally, and it's pretty standard to serve alcohol during these times. However, it's also worth thinking about the type of conference you're hosting and who'll be there. If the event is more formal or if you think there'll be a mix of people with different tastes, it's a good idea to offer a range of non-alcoholic options alongside the drinks. It's also important to ensure that alcohol service is done responsibly and to check the local rules or venue policies regarding drinking.
