However, the Opposition says it will continue to pursue Ms Bates over contact with lobbyists.
Today, the Opposition again targeted Ms Bates in Question Time, asking about meetings with former Brisbane mayor Sally-Anne Atkinson, which were not included in her lobbyist contact register.

"Unlike those opposite who believe we should be hermetically sealed in a vacuumed jar, speak to no-one about anything at any time," he said.
Former Liberal National Party MP Alex Douglas quit the party last year after he was replaced on two Parliamentary committees.
Dr Douglas, now the independent Member for Gaven, says he will not dispute the Speaker's ruling.
However, he has questioned whether the Ethics Committee has a future.
"Obviously a series of extraordinary things occurred and I would point out they certainly were not the norm," he said.
"My concerns now is whether the Ethics Committee, which is the oldest committee of Parliament, really has any further role."
Mr Stevens alleged that Dr Douglas himself had misled the House.
Dr Douglas and Mr Stevens were not referred to the committee either.
