THE plan to abolish family welfare bonuses for three million Australian children will smash Western Sydney families but barely touch the wealthy electorate of Prime Minister Malcolm Turnbull.

The Sunday Telegraph can reveal the number of children who stand to lose is more than three million nationally, figures ­tabled in parliament show.

Nine out of the top 10 NSW seats hit hardest by the federal government’s plan to abandon the annual $726 bonus for every child are in Western Sydney.

Families with the most to lose are in Labor MP Ed Husic’s seat of Chifley.

From next year, families will lose cash until the payment is abolished by 2018.

The changes will strip payments from 1.5 million Australians who meet the current income test for family tax benefit A and qualify for a $726 bonus every year.

Half a million of these families have combined incomes of $50,000 or less.

For a family with three children, the annual bonuses alone would be worth $2178.

But the impact could be higher if they qualify for family tax benefit B, which carries a $300-a-child yearly bonus.

Two electorates stand out as escaping maximum pain, with fewest families affected by the changes.

The top spot is held by Mr Turnbull’s blue-ribbon electorate of Wentworth in Sydney, and the second spot is held by his deputy Julie Bishop, the well-off seat of Curtin in Perth.

Each of the top five electorates with fewest low-income families are Liberal-held seats, including North Sydney, previously held by Joe Hockey.

Labor leader Bill Shorten said the figures on FTB A by electorate were proof that the cuts to families were unfair.

“He’s looking after his own backyard while making everyone else pay,” said Mr Shorten, who confirmed the ALP would back some of the changes to abolish FTB B to families when their youngest child turns 13.
