Mr Forrest lashed out at national media for publicising rumors of a merger between the Nationals and Liberal Party, saying he had more important tasks to complete.

Mr Forrest defended his party's role in Australian politics and said the review, commissioned by John Anderson and Michael Priebe, made good business sense.

"The reason for the review is we lost Dawson and we didn't win Flynn, both Queensland seats," he said.

"The reality is we didn't win Flynn because we didn't get the preferences from the Liberals, they went to Labor."

When asked if there was anything he would like to see come out of the review, Mr Forrest said he had `bigger fish to fry'.

"There's the Wimmera-Mallee Pipeline, which both the governments are not committing to, there's no rain, people still on EC, irrigators in the north have no allocations and then there are roads," he said.

Mr Forrest said it was disappointing both state and federal governments had backed away from their commitments to the pipeline.

"Whether they're playing hard-ball with GWMWater to try and get a cheaper price, I don't know," he said.

"But we need it finished completely. Had it been my government that said yes to committing that extra $25 million and then reneged, we would have been copping it from everywhere."

Mr Forrest said a major problem to be addressed in the review was financial resources to run electoral campaigns.

"We're talking six-figure sums and the government has changed the act to make it harder to receive private donations," he said.

Mr Forrest said he was sick of media speculation about a rumored merger.

"I've had conversations with journalists, across the country, and my answer is we've just won a seat in Gippsland," he said.

"Talks of a merger are a waste of time, it's not news. It is something that may or may not happen. We are just behaving in a responsible way like any business would do, and our business is representation."

Mr Forrest said the last Nationals' review was about 15 years ago.

"This review also highlights our strengths, like our motivated and supportive membership and committed team we have state and federal level," he said.

"The review is also about what is the best way to give rural Australia strong political representation. The people of north-west Victoria get strong representation. Is that egotistical? I'm not sure but that's what I believe."

Mr Forrest said he expected there to be a delay before results of the review were made public.
