If a minister wants to get a message through to the voters, they forget the dog whistle and go straight for the foghorn.
That tactic has been firmly in action this week, as the government declares that paedophiles, rapists and murderers will come into the country as a result of it losing a vote on the medical treatment of refugees.
Prime Minister Scott Morrison warns people-smuggling operations out of Indonesia will resume immediately, asserting that many more asylum seekers will start heading to these shores.
Australia may be an "immigration nation", but its politicians regularly return to the canon of the country needing stricter controls on who else is allowed in.
Amid the government's poor polling, its perhaps not surprising that Scott Morrison has seized the opportunity of putting border security back at the centre of the debate in the lead-up to an election expected in May.
Of course many voters may well care most about schools, hospitals and the basic infrastructure of everyday life.
In time they will be reminded about the state of the economy and the predicted budget surplus.
But in his recent speech to the National Press Club, Mr Morrison decided to emphasise all the existential threats he sees to Australia's prosperity.
He listed "radical Islamist terrorism; people smuggling; natural disasters; organised crime; money laundering; biosecurity hazards, cybersecurity" and half a dozen others.
In case there was room for doubt, he described the world as being "dangerous, uncompromising and, at its worst, simply evil".
The message was loud and clear: changing governments in May would put everything voters know and love at risk.
It's not subtle - and wasn't intended to be - as speeches have to break through all the noise and clutter of modern-day media.
But it sets the tone for the months of election campaigning ahead, as the politicians try to persuade voters they are the only ones to trust.
