Mr Goss, 63, will enter the Mater Private Hospital in Brisbane.

Previous neurosurgey occurred in 1997, 2002 and in February last year.

Mr Goss recovered well on each occasion and expects the same outcome from tomorrow’s surgery.

Family spokesman and former press secretary Russ Morgan said Mr Goss preferred to keep the matter low-key.

``He’s in good spirits, positive and has retained his sense of humour about the situation so that in itself is quiet an achievement,’’ Mr Morgan said.

Mr Goss won the 1989 state election against the National Party government of Russell Cooper, with the conservatives in disarray after revelations of widespread police and political corruption exposed during the Fitzgerald Inquiry.

Mr Goss was educated at Inala State High School and became a solicitor before entering politics.

In Government he started a major reform program, getting rid of the gerrymander that had helped conservative forces stay in government for decades, decriminalised homosexuality and introduced environmental regulations.

Mr Goss’ chief of staff was former diplomat Kevin Rudd who later became prime minister.

Goss won a second term in 1992 but before the 1995 election announced a plan for a toll road between Brisbane and the Gold Coast that would run through the state’s largest remaining koala colony.

It prompted huge protests and cost Labor four seats which put the government on a knife edge. A byelection saw a hung parliament and the Rob Borbidge conservative government - supported by Gladstone Independent Liz Cunningham - took control.

Peter Beattie took over leadership of Labor and easily won the following election.

After retiring from politics, Mr Goss worked with accountancy group Deloitte Touche Tohmatsu and in other roles.

In 2007 Mr Goss became the first Queensland politician to have a group of plants named after him _ the genus Gossia.

He was honoured because of his governments’ conservation work that included Wet Tropics World Heritage listing, introducing the Queensland Nature Conservation Act for the protection of threatened species, stopping rainforest logging and extending the national park estate.

Mr Goss joked at the time that he never expected such gratitude when he approved spending for a new herbarium building.

And when I told my family, they unanimously said I didn’t deserve it,’’ he said.
