Sexting Queensland MP Peter Dowling won't be referred to state parliament's ethics committee over failing to declare travel upgrades.
The Redlands MP gained worldwide notoriety after his mistress wrote to parliament last month to reveal their affair.
She confessed the pair had sex in his parliamentary office and he texted her a photo of his penis in a glass of red wine.
The mistress also alleged Mr Dowling took advantage of parliamentary travel trips to meet her in locations including Perth and New Zealand.
During these trips he accepted more than $20,000 in free upgraded flights, which he didn't declare on his members register of interest.
However, Speaker Fiona Simpson told parliament on Tuesday he didn't have to.
Other allegations raised in the letter are still being considered by the clerk of parliament, she said.
"The schedule is silent about the need to report to the house in this circumstance," she said.
"However, the clerk's view is that due to the complaint letter having been tabled in the Legislative Assembly and publicly reported on, it is both in the public interest and in fairness to the Member, that the outcome of this particular matter be reported to the house."
Mr Dowling stood down as chair of parliament's ethics committee after news of the scandal broke.
