@Transportist Thinking about it as well, feel like I should know something from my bridge building days but can't remember.

According to this: https://austroads.com.au/publications/bridges/abc2017-133-17/media/ABC2017-133-17_Ross-Pritchard-2017-Revision-of-Australian-Standard-AS5100-Part2-Design-loads.pdf "Ship impact loads for navigable waterways and fire loads have been included for the first time", in AS5100 in 2017.

Ofc doesn't mean they weren't considered before, but not based on AS. Couldn't find anything from TfNSW either which was surprising.
