The debate will be fiery and some MPs may vote against it, but the Baird government's controversial bill to end greyhound racing in New South Wales is expected to pass this week.
The legislation, which will ban the sport from July next year, will be debated in parliament's lower house on this afternoon with a vote expected later in the night or tomorrow.
Nationals MP Kevin Humphries on Friday confirmed he would cross the floor over the bill, warning it will devastate regional communities.
The member for Barwon is one of a handful of Coalition MPs who have publicly argued against the ban.
The Nationals' Katrina Hodgkinson, Melinda Pavey and Chris Gulaptis have previously indicated they cannot support the legislation but it's not known if they will vote against it.
The Greyhound Racing Prohibition bill, which includes a one-year jail sentence and maximum $A11,000 ($NZ11,500) fine for anyone caught organising a race after the ban, was fast-tracked through parliament last week.
The proposed laws will also forbid people to export greyhounds to other states without the written consent of Greyhound Racing NSW before the ban takes effect.
Labor is opposed to the legislation but it's likely it will be swiftly passed with the support of the Greens.
The state government has meanwhile confirmed it spent close to $A1 million on a series of advertisements promoting the ban.
The price tag was less than one per cent of the government's annual advertising budget.
Premier Mike Baird has stood firm on his decision to end the sport since his announcement last month, saying he had "no choice" after a Special Commission of Inquiry report revealed widespread animal cruelty within the industry.
