Labor says it will be up to the Turnbull government to prosecute the case for why findings from the botched census should be trusted when the first batch of data is released next week.
Opposition spokesman Ed Husic won't commit his party to endorsing the data drawn from last year's shambolic census, which crashed online for some 40-hours because of cyber attacks.
"It'll be dependent on the government explaining why this data should be trusted - what they've done in the meantime to provide quality assurance in the whole process," Mr Husic told ABC radio on Thursday.
Mr Husic took aim at Prime Minister Malcolm Turnbull, who last year described the bungled census as "utterly predictable, utterly foreseeable."
"Well if that's the case, why didn't someone in government predict it? And why didn't someone with as much business tech-savvy as the prime minister be able to detect it?" he said.
The census, mostly conducted online on the night of August 9, was marred by cyber attacks which prompted the Australian Bureau of Statistics to shut it down for almost two days.
IT company IBM paid out millions in compensation for its role in the botched survey.
