POLICE have defended taking nearly five days to tell Ipswich residents the full story behind a residential chemical explosion last Thursday night.

Three men were injured, one critically, in the Clay Street blast and the bomb squad undertook 14 controlled explosions between Thursday and Monday.

Another explosion was being carried out on Tuesday morning.

However, police gave away little information publicly until Monday, causing significant anxiety in the neighbouring community, according to Ipswich City Council's Andrew Antoniolli.

"The police need to do their job, they need to make this safe, however, there is some anxiety from people in the area heightened by this action," Cr Antoniolli told Fairfax Media.

"There are huge question marks out there. What were these guys up to? What was their intent? As a public we really need to know."

Ipswich police Inspector Keith McDonald defended not revealing more publicly until Monday.

"The full story started to come out on Friday when we found more and more material as the investigation and search has continued," he said.

"The thing people have to understand is before we hand the property back to the owner and real estate agency, we have to make sure to the best of our ability we have taken all steps to search the property thoroughly because there is a high risk associated with this material."

Inspector McDonald said the search of the area after Thursday's blast uncovered large quantities of the chemicals - much more than was initially anticipated.
