Sorry to jump in on your 'Melbourne Outing' thread but as you are planning things around Easter, and you seem to be large format users, I thought you may want a suggestion.
Goldstreet Studios at Trentham is hosting the Australian Alternative Photographic Process Symposium at the start of April. Several very experienced people from around Australia and overseas are speaking and running workshops. The famed daguerreotypist Jerry Spagnoli from New York will be there for one. This will be the biggest event of its type to be hosted in Australia.
If you are at all interested then you can find some information on the Goldstreet Studios site:
Have fun at your outing.
