Taxpayers paid $13,600 for a now-shelved 12-metre sign and scaffolding to commemorate former Labor deputy premier Terry Mackenroth at Suncorp Stadium.
But Sport Minister Mick de Brenni lashed out at the LNP's questions about the proposed new name for the stand during estimates, arguing it was "morbid".
In July, Premier Annastacia Palaszczuk announced the stand would be named to commemorate the former politician, known as "The Fox", who died in April and was a leading player in the redevelopment of the Suncorp Stadium.
However, within a week, Ms Palaszczuk announced she was scrapping the plan after his family was surprised, hurt and disappointed by the reaction.
After criticism, Ms Palaszczuk tried to downplay the issue, arguing it was just a "small panel" and the situation was a "storm in a teacup".
But following questions from LNP sport spokesman John-Paul Langbroek during estimates hearings on Friday, it was revealed the sign for the third tier of the eastern grandstand was 12 metres long, with letters 600 millimetres high.
Mr de Brenni said Stadiums Queensland had advised the letters on the sign could be changed and it could be used in another location.
"I do sincerely hope this concludes the extended run of political mileage made off the death of a great Queenslander," he said.
"The sign would have been a fitting honour of his contribution to Queensland, it hasn't proceeded and as far as I think all Queenslanders are concerned, that should bring closure to the matter."
Mr de Brenni said he wanted to remind Mr Langbroek about the anguish already felt by Mr Mackenroth's family, and described his line of questioning as "bizarre and morbid".
Mr Langbroek said there was no reflection on Mr Mackenroth's family and he was just trying to clarify details about the sign.
There was later a fiery outburst after LNP member for Callide Colin Boyce began wheeling out a tape measure during a description of the dimension of the sign's letters.
"Not only is it a prop, this is a disgusting display," Mr de Brenni said.
"May the record reflect the disgusting behaviour that's being shown by the members of the opposition in relation to this matter - you should be ashamed of yourselves."
Politicians are banned from using props during sittings of Parliament and estimates.
The sign is in storage with the sign contractor, with plans for it to be moved to a Stadiums Queensland venue for storage.
Mr Langbroek argued Ms Palaszczuk's call to name the stand after Mr Mackenroth was out of touch and "insensitive to the grief" of his family.
"The whole saga became a debacle and it took far too long for Annastacia Palaszczuk to drop the idea," he said.
Meanwhile, Labor backbencher Jo-Ann Miller asked Mr de Brenni if the government could investigate any private email accounts used by Ipswich councillors for official purposes, tabling media reports about Councillor Paul Tully's Gmail accounts.
"Can you provide advice to the Ipswich City Council and other councillors across Queensland in the use of these emails?" Ms Miller asked.
"I think they're in desperate need of guidance."
Mr de Brenni said his department could provide advice to public authorities on appropriate record-keeping practices but investiating emails was up to the Crime and Corruption Commission.
