Here's what it means in plain English:
"Penalty units" is how the Australian government sets fines. Instead of updating dollar amounts in every law every year, they set fines in "units" and adjust the dollar value of a unit once a year.
Currently, 1 penalty unit = $222 AUD.
So 10,000 penalty units x $222 = $2.22 million.
But here's the kicker… it's per day.
That means if ACMA finds you're sending non-compliant SMS and you've been doing it for a week, they can theoretically fine you $2.22 million x 7 days = $15.5 million for that one campaign.
In practice, ACMA doesn't always hit the maximum. Recent fines have been:
So the $2.22M/day figure is the legal maximum, not what every business gets fined. But ACMA is getting more aggressive. The total penalties in 2025-2026 alone were over $5.4 million.
