No campaign outspends Yes, despite its claims
SAME-sex marriage opponents have spent twice as much as Yes campaigners on television advertising, despite claiming they would be fighting a "David versus Goliath battle”.
The estimates come as reports emerged of "Vote No” graffiti and swastikas being scrawled across public transport in NSW, and rocks being thrown at houses flying rainbow flags.
The Coalition for Marriage is the leading No campaigner and it is believed to have spent almost $1 million on TV advertising to date.
The Equality Campaign has spent $494,000 on television ads.
The analysis comes from marketing analytics firm Ebiquity as the campaign enters its eighth week since Malcolm Turnbull's announcement of the government's intention to hold a postal survey.
The analysis doesn't include costing of tactics such as the Yes campaign's mass text message at the weekend, but the firm's monitoring of press, television and radio advertising indicates gay marriage advocates are being outspent.
The two leading Yes groups, The Equality Campaign and Australian Marriage Equality, have collectively spent about $849,000 on two print ads, six television ads and three radio ads.
The Coalition for Marriage has put out just four television ads but, based on Ebiquity's estimates of advertising market costs, the cost would be about $994,000.
That includes the controversial "You can say no” ad with Sydney GP Pansy Lai, mother of four Cella White and pastor Heidi McIvor.
Coalition for Marriage spokesman Lyle Shelton had previously claimed the debate would be a David versus Goliath battle for gay marriage opponents given the number of big businesses that have publicly backed changing the law.
