Opposition spokeswoman for transport Candice Burch moved the motion to censure Mr Steel for his "failures" in implementing the new weekend bus service in the Legislative Assembly on Tuesday.

The censure motion did not gain the support of the Greens needed to pass.

Instead, an amended motion moved by the Greens, which removed the censure of Mr Steel but noted the government's failure to deliver reliable weekend services, passed with the government's support.

That motion called on the government to urgently examine innovative options to deliver the promised level of services with a lower number of drivers.

The government has struggled to service its new expanded weekend bus service, launched at the end of April, due to driver workforce issues.

Mr Steel on Friday moved to temporarily cut a number of weekend services to improve reliability.

Greens MLA Caroline Le Couteur said it was not fair to put the blame for "the disaster" on Mr Steel who had only been in the role for about two months.

She said if someone was to be censured it would have been the former Transport Minister Meegan Fitzharris.

Ms Le Couteur said the decision to cut some weekend services without telling the Assembly when discussing the issue days earlier was "disappointing and incredibly disrespectful".

"He didn't wake up at 5am on Friday and say, 'oh look I've got a solution'," Ms Le Couteur said.

Labor frontbencher Mick Gentleman told the Assembly Miss Burch's motion was "nothing more than a stunt".

He claimed the Liberals would privatise services like buses if elected next year.

Mr Steel said changes to the bus network on such a magnitude had been a challenge and conceded the weekend service had not met community expectations.
