Can't find the more attribution focused talk (see he's given it a few times but can't find the slides - think I found them once searching through slideshare.) Here is one Willem did which is probably a bit too brief to get much out of (was at a CDO conference) https://www.slideshare.net/Corinium/foxtel-at-the-chief-data...

Another two: https://www.cmo.com.au/article/630808/exclusive-iag-columbus...

Another talk synopsis here which might provide some insight https://www.meetup.com/Web-Analytics-Wednesday-Sydney/events...

Willem is the person I know in Australia who has put the most effort into this stuff and has been able to talk about it.
