The bill, moved by Bass Greens MHA Kim Booth, sought to introduce a state-based $1 bet limit.

``This was a day where Tasmania could have succeeded where Ms Gillard and Mr Wilkie failed,'' Mr Booth said.

Gaming Minister Scott Bacon defended the move, saying Tasmania was ahead of the curve.

``Tasmania has introduced a range of harm-minimisation measures in response to the findings of the first social and economic impact study of gambling,'' Mr Bacon said.

Such measures include training in recognising and dealing with problem gamblers, providing clocks, minimum lighting standards and display of help signs in restricted gaming areas.

Anglican Bishop John Harrower supported the bill, saying hundreds of millions of dollars were ``harvested'' from Tasmanians every year.

``I am saddened that both Labor and Liberal members are not willing to pursue poker machine reform at this time. I call on both major parties to change their priorities in this area,'' Reverend Harrower said.

Independent Denison MHR Andrew Wilkie said the $1 bet limit was a flagship recommendation of the Productivity Commission.

``Labor and Liberal appear to be completely beholden to the gambling industry and seem to care more about gambling interests than the public interest,'' Mr Wilkie said.

Denison Greens MHA Cassie    O'Connor accused the Liberals of having a ``hollowness'' for not supporting the measure.

``The profound social and economic cost of the current gambling regime . . . is very significant for those Tasmanians, particularly in areas of high socio-economic disadvantage,'' Ms O'Connor said. 

The Greens attacked the Liberals for not supporting the bill, when the party supported a measure in 2009 by former Braddon MHA Brett Whiteley.

The 2009 motion did not become law as the majority Labor government voted against it.

Liberal spokesman Jeremy Rockliff defended his party's non-support, saying a Tasmanian select committee recommendation did not support the bill, and that it ensured job losses.
