The commission's single biggest campaign so far has been "Don't be a vote ghost", which according to Facebook stats was targeted at the 18-24s and 25-34s.
"Reminiscent of the famous "Ghost Chips" anti-drunk driving campaign, the ad is all about encouraging young people to enrol and vote," Dorrian says.
A "don't be nervous about your first time" double-entendre effort was targeted mostly at the 18-24s, though also served to a number in the 25-34 bracket.
An ad based around the cannabis referendum - a useful vehicle to try interest around in enrolment - was also heavily targeted to those two demographics, though the commission also spent a smattering to reach older Facebook users.
So is it all working?
The Electoral Commission's most recent figures, released on September 30 - just over a fortnight from the election - show 72.4 per cent of 18 to 24-year-olds have enrolled to vote.
It remains to be seen how many actually vote, but that's a better base than 2017, when 69.3 per cent of 18-24s had enrolled by election day.
Similarly, an estimated 79.57 per cent of 25 to 29s have enrolled this year, compared to 67.56 per cent in 2017.
