23 April: Vandals defaced a Liberal Party billboard in Perth just hours after it was unveiled by Opposition Leader Tony Abbott.
The billboard claimed more than 600 “illegal” asylum seeker boats have arrived in Australia since the Labor Party won government.
The number has since been whited out and replaced with a zero.
Also spray-painted on the billboard were the words: “No crime to seek asylum.”
The sign has subsequently been replaced with a previous Liberal Party add.
