I'll happily add to it.
Before I was deputy minister, I was acting national security adviser through the most recent election. I was also acting national security adviser in the period after the 2019 election. There is, as has already been said, a kind of baseline level of foreign interference or attempted foreign interference at all times that we need to be vigilant on.
My experience as national security adviser in those key periods was that there was no spike in foreign interference, that I'm aware of, in either the 2019 election or the 2021 election.
