Former NSW Labor MP Karyn Paluzzano, who falsely claimed parliamentary sitting-day relief payments, has been sentenced to at least one year of home detention.

The 52-year-old former Penrith MP pleaded guilty in June to falsely claiming parliamentary sitting-day relief payments between 2006 and 2007, as well as giving false and misleading evidence to a 2010 ICAC (Independent Commission Against Corruption) inquiry into the payments.

In the Downing Centre Local Court today, Deputy Chief Magistrate Jane Culver said Paluzzano's "repeated breaches of trust" merited a maximum custodial sentence of 18 months.

But she said the custodial sentence could be served by way of home detention, pending the outcome of an assessment report.

Paluzzano showed no reaction as the decision was handed down.
