New figures obtained by the ABC indicate that taxpayers are paying hundreds of thousands of dollars yearly for the decontamination of drug laboratories found in government housing.

It was found that over the last two financial years alone, taxpayers paid more than $550,000 to decontaminate about 140 houses in Queensland, but the offending tenants are not being banned from reapplying for a house.

Although tenants are evicted for this misconduct, reapplying for housing is not prohibited under public housing policy.
