Abbott focused on budget, not gay marriage

Prime Minister Tony Abbott has indicated he won't be supporting Labor's offer of bipartisanship on Bill Shorten's same-sex marriage bill.

The opposition leader has given the government the opportunity to second the bill that he is due to introduce to parliament on Monday, rather than Deputy Leader Tanya Plibersek.

"I've made it very clear that while this is an important issue the government has an absolute focus right now on getting the budget measures through parliament," Mr Abbott told reporters in Sydney on Sunday.

Queensland Liberal Warren Entsch, a supporter of gay marriage, will not co-sign Mr Shorten's bill.

But he has told Fairfax media he has agreed to meet with Mr Shorten after the budget sittings that end on June 25, to try and come up with an "all parties" solution.

Confirmation was sought from Mr Entsch's office.
