Last week the News obtained figures from ClubsNSW estimating West Pennant Hills Sports Club, Glenorie RSL and Castle Hill RSL could lose a combined $11 million in revenue due to the reforms.

Mr Reed said he was not aware of the estimated cost the reforms posed, but said any change to the current laws would be highly detrimental to clubs.

"We're a medium-sized club and I can tell you this would certainly hit our members in the hip pocket," he said.

The reforms include mandatory self-spending limits and state-wide lock out periods on poker machines.

Clubs will also be required to update their now defunct poker machines with new models, costing about $22,000 a machine.

"We only just upgraded our machines in 2000 to adhere to new state legislation," Mr Reed said.

According to ClubsNSW, West Pennant Hills Sports Club stands to lose $3.6 million in installation costs and lost revenue.

A spokeswoman for federal minister Jenny Macklin said the reforms were necessary because problem gambling destroyed families and ruined lives. "The government is committed to introducing changes in gambling venues to reduce the impact of pokie addiction in our communities," she said.

"We know that small pubs and clubs in the suburbs just aren't the same as the big gambling venues.

"That's why the Australian government will ensure that small venues with 15 pokies or less will have more time to get ready for pre-commitment technology."
