Hey, due to ACCESS-NRI/build-cd#173 we have had to update the infrastructure in this repository, as well - see #28.

We try and keep these kinds of updates to a minimum, and, starting from this one onwards, it will no longer be a hard requirement to update PR branches to incorporate infrastructure changes in order for the infrastructure to work - as you need to for this one.

To update this PR to the new origin/main, do the following:

git pull
git rebase origin/main
git push --force

to incorporate CI changes into the PR.

Your PR may redeploy, but that is okay - it should be identical to the last deployment. Let me know if you have any questions or issues.
