Ms Gillard would not directly comment on results of a Fairfax/Neilsen poll released on Monday, which shows 29 per cent of voters support Labor - down two per cent from a month ago - and Opposition Leader Tony Abbott has gained more ground as preferred prime minister.
"Ask me about the $14.5 billion dollars for schools - they're the only numbers that are worrying me," Ms Gillard told the Nine Network on Monday after talking up her government's proposed education funding reform scheme.
She repeated the same general lines during a later interview on Australian Radio Network when asked about the poll numbers.
