Mr Green acknowledges that he has agreed to meet the Bruno Manser Fund during its impending visit to Tasmania.

According to its website, the fund is committed to protecting tropical rainforests and people who inhabit them.

Bruno Manser, the founder and president, spent several years living in the Malaysian state of Sarawak.

The Greens have highlighted and questioned operations carried out in this area by Hydro Tasmania's Entura business.

A spokesman for Mr Green said he would use the opportunity to explain Entura's Malaysian operations.

Greens energy spokesman Kim Booth, who has led the charge against any Tasmanian involvement in dam building in Sarawak, has agreed to tour Entura's offices and meet staff with Mr Green.

Those commitments are outlined in a letter that Mr Green sent to Greens Leader Nick McKim after months of negotiations between the parties on energy reforms.

The Greens have now committed to voting for the government's raft of reforms.

Yesterday in Parliament the Opposition's energy spokesman Matthew Groom demanded to know what the real, secret deal was between the parties.

He said it was clear that Hydro's mainland retail business Momentum Energy would be sold in exchange for the Greens' votes.

Mr Green said Momentum's operations would be monitored by the government, including its financial records and market exposure and risks, in line with the reforms already announced.
