So I packed them with 4 large sealed ice blocks around them, and then wrapped them all together in bubble wraps, and placed them in a chiller bag, and then in a suitcase (in an air conditioned place).
They survived Australian heat (height of summer) and Singapore heat OK, and did not have any sign of melting.
By the time I reached the destination approximately 24 hours later, the chiller blocks had melted completely, but they were still quite cold. They did the job while they were needed. No concerns at the destination - norther hemisphere winter.
