As we head towards the end of March, the close of early bird registration savings, and with the scientific program underway, I am excited to release some details regarding the IUCr 2023 Social program.

Australians are renowned for their socialising and we love nothing more than a good party with friends, lots of food and laughter.

For the duration of the Conference, daily morning, lunch, and afternoon tea breaks are included in your registration fee. The traditional Welcome Function will be hosted at the Melbourne Convention and Exhibition Centre amongst our valued sponsors and exhibitors. We plan to provide some Australian treats and fine beverages on this occasion.

Rounding off the social program and celebrating the near end of the Conference on Monday, 28 August, we will host the Gala dinner event “A Night at the Museum”, at the famous Melbourne Museum. This is not an event to be missed. We promise this will be something special and includes access to the Dynamic Earth Exhibit, which is befitting for a dynamic crystallography group. All social functions, plus catering and transfers, are included in your registration.

For our international guests, remember that Australia does not have any additional taxes on the quoted price; it just includes a 10% federal tax you can claim eligible expenditure back at the airport via the Tourist Refund Scheme. For accommodation, the price quoted is the final price you will pay for the room you book through the Conference Secretariat.

While you’re planning your journey, please also consider taking advantage of the destination to visit some of the local and totally unique Australian locations.

The Full IUCr 2023 Congress Program is now available, so you can start to plan your schedule! Personally, I am excited to witness our Plenary, Keynote and Invited Speakers across the Congress program, who come from all areas of the crystallography field, and are experts in each of their respective areas.  I am also thrilled by the quality of the various abstract submissions that have been accepted as orals and posters for the Congress and look forward to the presentations that are to come.

We look forward to all the Program has to offer and look forward to you joining us in Melbourne in August.

Gender equity and diversity

The IUCr is committed to achieving gender equity and diversity (that mirrors our crystallography community) in all its endeavours and activities. A key aspect of the IUCr mission is to ensure our community fosters inclusion, ensures mutual respect, and embraces diversity. To help achieve its diversity goals, the IUCr has developed a code of conduct which applies to all its endorsed or funded activities.
