Super for homes chatter goes in circle: PM

Malcolm Turnbull won't contribute to debate on allowing young Australians to use superannuation savings for a house deposit that has split coalition MPs ahead of the May budget.

"This is a debate that's gone round and round for a long time," the prime minister told reporters in Mumbai on Wednesday, where he was wrapping up a three-day visit to India.

"I've read all of the speculation; standing here in Mumbai I won't contribute to it although I've expressed fairly strong views about it in the past."

Previously, Mr Turnbull has described the idea as "thoroughly bad".

His government is planning to make a housing affordability package the centrepiece of next month's budget.
