Hi Jaclyn, we held our Melb reunion a couple of weeks ago. We have held it at Young & Jacksons (https://www.youngandjacksons.com.au/ – opposite Flinders St Station) for the last decade or so. We have a private space on the first floor and this year had 50-odd attend. The staff are great, food excellent and they have a really good audio setup for speeches. Can highly recommend them. Please feel free to reach out directly if we can assist further. Good luck!
